Nov 10, 2009 8:24 PMWhy the mainstream media is dyingfrom The Secret Diary of Steve Jobs by Steve100+ people liked this

Every once in a while you get to see a mainstream outlet cover a story right alongside a blog, so you can put them up against each other and see why one was so much better than the other. This week TechCrunch and the New York Times (photo) provided just such a lesson.

The issue was a company called Zynga, which makes online games, like FarmVille, that have become incredibly popular on Facebook among people who are missing parts of their brains. On Oct. 31 TechCrunch broke a big story called "Scamville: The Social Gaming Ecosystem of Hell" about how Zynga was making money by selling scam ads -- the kind that trick kids and other frigtards into signing up for useless subscriptions to stuff they don't want.

Arrington packaged his story with a video of himself taking on Anu Shukla, CEO of one of the scam-ad distributors, at a conference. He also ran an "insider's confession" piece by a former scammer explaining how these guys operate. He followed with a story about how Zynga CEO Mark Pincus had acknowledged the problem and said Zynga would stop running those ads, and another story about how Anu Shukla had been pushed out of her company, and another story about Shukla's replacement admitting that the company had, indeed, been running scammy ads. On Friday Arrington capped it off with a coup: he dug up a video clip from earlier this year in which Pincus, the CEO of Zynga, told a laughing audience of scumbag developers about all the scumbaggy things he had done to generate revenue with his games.

After all this, we woke up Saturday to find a story in the New York Times, also about Zynga (and other Facebook game companies) with the headline, "Virtual Goods Start Bringing Real Paydays." The Times put two reporters on the knob-polisher, and somehow they managed to interview Pincus, and to quote him -- and yet they included not a single word about the scammy ads. Not. A. Fucking. Word. The piece could not have been nicer if it had been written by Zynga's PR people themselves. Gist: Virtual goods, stupid idea, people play, some spend money, VCs love it, isn't this great.

Ahem.

So: they walked into this shit-storm and somehow, by some miracle, managed not to notice the fecal matter flying all around them. It's like covering a football game that took place in the middle of the blizzard and neglecting to mention the weather.

Now, maybe they did all the reporting before Arrington's stuff broke. In which case they should have gone back and updated their info. Or maybe, just maybe, Zynga's PR people teed up a Times story as a kind of rebuttal to what Arrington was reporting. Either way, that's what ended up happening: Zynga used the Times to deflect the bad shit flying at them from Arrington. They need good press because they're hoping to cash out by going public next year. That story in the Times will be worth millions. Many millions.

Meanwhile, Arrington, still digging, blasted again on Saturday night, reporting that sleazy ads had popped up again on Zynga, despite promises that they would be taken down.

Um, New York Times? If you guys are still wondering why people are dropping their subscriptions and getting their news from blogs instead of you -- this is why.

And to all those people who go around wringing their hands and saying what are we going to do when the "real newspapers" all die and we have to get our news from Gawker and HuffPo and TechCrunch? Friends, I think we're going to be just fine.

Part of it is the form of the media itself. If you're a reporter at the Times, you get one story, and a fixed number of inches, and you're smothered by layers of editors. At TechCrunch it's one guy who can get his teeth into something and there's no limit on how many articles he can do.

What really cracks me up is how often I still hear people say that bloggers are mere "aggregators" and the "real journalism" gets done at places like the Times.

Because time after time, blogs are simply beating the shit out of the newspapers. They're the ones who still dare to go for the throat, while their counterparts at big newspapers just keep reaching for the shrimp cocktail.

As for the newspapers: Faced with their own demise, fearful of losing even more advertising, newspapers have made the huge mistake of becoming ever more timid, more cautious, more in bed with the companies they cover.

It's the exact opposite of what they should be doing. The truth is, if newspapers want to survive they should go back to doing what they started out doing -- muckraking, stirring the shit, calling bullshit.

The other truth is, when these papers are dead, they will not be missed.

Nov 10, 2009 8:24 PM25 Link Building Tactics to Improve Blog Search Engine Rankingsfrom Online Marketing Blog by Lee Odden100+ people liked this
Blogs are often touted as good for search engine optimization. The reality is, blogs are simply software tools and what you get out of them from a SEO perspective is in proportion to how well you know how to use them. Good keyword categorization and content are a start, but blogs are not much of a SEO asset unless they attract links.

The myth of “Build it and they will come”. Not many businesses that start blogs have the patience to create great content and wait for others to find that content all on their own as a linking strategy. Without clicking on a link or finding it on a search engine, how will others find your blog? Content is King but only if you promote it.

Links from relevant, credible sources balanced with on-page keyword optimization make it easier for search engines to find, index and sort blog posts in search results. If there’s an expectation for a company blog to rank well in search results, be sure to consider some of the following link building tactics:

1. Create content worth linking to. No matter how many tactics you find here and elsewhere, there simply is no substitute for creating content that others may find useful. Take the time to look at blog posts that already rank well in search results and notice their structure, quantity of words and word placement.

2. Conduct backlink analysis on competing web sites or blogs – find out who is linking to competitor sites that are not linking to yours. Ask sites linking to multiple competitors to link to yours as well. If another web site or blog is already linking to multiple competitors, there is a chance they’ll link to your blog as well.

3. Make useful comments on other blogs that don’t have rel=nofollow. Comments should always be useful, but if you become aware of a topically relevant blog that does not discourage search engine spiders from crawling links in comments, it’s work spending the extra time to provide helpful insights a links to resources that you’ve published on your own blog.

4. Encourage social bookmarks & news submissions of your content using services without rel=nofollow. Show links to those services like Folkd, Spurl or Feedmarker in the blog post template code so they are visible for blog readers to use. Some social bookmarking services will make a copy of what you bookmark or a static web page of the bookmark including a do follow link back to the source (your blog).

5. Get listed on other blogger’s blogrolls. It never hurts to ask another blog that you’re active with to see if they’d consider adding your blog to their blogroll or curated lists of blogs.

6. Guest write on other blogs and include a link to your blog in the bio. In the course of getting to know blogs that already rank well on the keyword phrases you’re targeting, you may notice that they often accept guest blog posts from others. Contact the blog owner and suggest a compelling post that would be first and foremost, valuable to their readers. If it makes sense editorially to link from within the guest post to your own blog, be sure to use relevant keywords as the link text.

7. Submit to blog & RSS directories. Many directory links have no follow links or are not visited by a large volume of people, but making sure your blog and RSS feed are included in niche categories and collections of blogs can be a positive signal to search engines as well as to long tail users. Many bloggers that aggregate large lists of topically specific blogs will cultivate blog directories as a easy way to find blogs on similar topics. If your blog isn’t on the niche list in those situations, you won’t be included.

8. Submit to regular web site directories like botw.org. While there are blog specific directories (BOTW has one of those as well) many don’t discern web sites from blogs. If a quality directory has a relevant category with other reputable web sites in it, then it makes sense for your blog to be among them as a useful information source.

9. Be sure to include your blog URL in profiles and bios on social media sites. While most social media sites that allow users to add links to their profiles add no follow to the links, there are many that do not. Public profile links on LinkedIn and YouTube channels for example, are good links. Rather than focus on registering with 300+ sites using Knowem, just make sure that of the social media profiles you do set up inlcude a link back to your blog.

10. Write testimonials for services and software that you use. They may publish with a link back to your blog. Testimonials must be well written, genuine and specific in order to be useful for the service/product owner. Get at the essence of what’s great about the product or service and even add something unique. If you’ve written a review of the product/service on your blog, that can also get you a link from their press page.

11. Job listings should always have a link back to your blog. Blogs can be useful recruiting tools that help candidates understand the culture of your company. When purchasing job listings on other web sites, add a link to your blog. The listings may expire, but may also introduce your blog to candidates that write their own blog and decide to write about a listing with a permanent link to the hiring company blog.

12. Event listings should always have a link back to your blog. Blogs can be effective tools for promoting events and if you are listing your event with 3rd party services, a link back to your blog post with more details will be useful to readers that want to know more. That link can also be useful to search engines.

13. Contributions to non-profits often have a donor page with a link. These links are now very rare but you should contribute anyway.

14. Article syndication can still result in a few good links. Include your blog URL in the article bio. Take some of your best tips oriented blog posts and re-write them for specific industry verticals or applications. Then submit them to article repositories. When others re-use those articles, the bio link back to your blog can be picked up by readers and search engines.

15. Distribute press releases via a wire service with a link to your blog included. Our client, PRWeb, is a pioneer in providing competitive SEO value with press release distribution. Many blogs and some news web sites will re-publish your press release exactly as it was distributed, including good links back to your blog. Journalists use News search to look up past press releases and research on stories, which presents an opportunity to be found and included.

16. Contribute Op Ed pieces to Mainstream Media web sites. Contribute a link to your blog of course. If you suggest content to another web site such as a letter to the editor, why not keyword optimize the title? Why not include a link back to your blog where you’ve written many more articles on the same topic?

17. When you get media coverage (or placements) in online publications, be sure to ask the journalist for a link to your blog. Again, it never hurts to ask. Many publications have a policy not to link out from stories. Many leave it up to the journalist or their editor. If you don’t ask, you will never get the link.

18. Develop social networks and share especially useful content from your blog where relevant. Be useful to others and they will useful to you by promoting your content and attracting links. Don’t be gratuitous when sharing links to your own content, but when you have something particularly special and valuable that’s highly relevant to a particular network, then by all means, share it with them. Some are bloggers as well and may link to it from their own blogs as well as pass the link along to others.

19. Linkbait. Create or aggregate disparate content that provides value and is not easily found elsewhere. Promote it to those that would be interested and in a position to distribute to the right audience. Again, create useful content, but be thoughtful about packaging it in a way that makes it unique and is easy to pass along. Look at other blog posts in your topical category that have “gone hot” on social news sites and understand their structure, format and tone. Leverage what has worked for others in your own content to be promoted.

20. Sponsor content on web sites or newsletters archived to the web that allow you to include a link. It may be a nofollow link, but it may not. Many newsletters sent via email are archived to the web or have landing pages on the web. Ask those newsletters if you can buy an ad or even contribute a short article. The article credits should include a link to your blog.

21. Hire bloggers to write content for you. They’ll often cross-post it to their own blog with a link back to yours. Of course, you should be considerate and simply mention that this is ok, don’t ask them or require them to do it.

22. Run a contest that may involve others deciding to link back to your blog. This can be tricky, but Marketing Pilgrim does a great job of this with their SEM Scholarship Contest. Readers write blog posts and the first cut is based on which posts get the most traffic and presumably, links among other criteria.

23. Offer a widget, when posted to others’ web sites, includes a link back to a credits page for the widget on your blog. TopRank’s Thomas McMahon created a RSS buttons tool and it’s use by other blogs has resulted in over 322,000 inbound links.

24. Review other blogs and offer a badge for those that get included. We’ve done this with BIGLIST and it has resulted in over 64,000 inbound links. Focus on quality and be consistent. Also offer a version of the badge that does not include a link for those that want to display the “blog flare” but don’t or can’t link to it. You should include your logo on the badge for improved brand awarness whether there’s a link or not.

25. Create an exceptionally useful tool. Others will link to it simply because it is useful. (See step 1) TopRank created a Social Bookmarking Tool several years ago and still has over 50,000 links as a result.

Bonus tip: When others link to you, THANK THEM! Building good will is one of the most underrated marketing skills online. Be genuine, thoughtful and courteous. Also be SMART and driven to get links where it makes sense.

What linking tactics for blogs have you found to be most effective? What challenges are you facing in attracting other sites to link to your blog?

Nov 10, 2009 8:24 PMHoney, I Tattoo’ed The Kidsfrom harry ... the ASIC guy by harry
I may be the engineer in the family, but my wife is the inventor.

Being an engineer is easy. You go to school to learn well established laws and methods. When you get a job, there are others who can mentor you and show you the ropes. If you need to know more, there are training classes to take. Someone else, usually marketing, decides what needs to be to be designed. All you have to do is follow the rules.

Being an inventor is hard. There is no school for inventing, nobody to teach you the ropes, and no classes to tell you how to do things. You come up with your own idea that has never been done before. You learn on the fly what you need to know from a variety of domains you know nothing about. You build it yourself. There is no such thing as first pass success. Experimentation and refinement are a constant process.

For those of you who know Joyce and have been privileged to receive one of her hand-made personalized holiday “greetings”, you know that she is one of the most creative and gifted people you could ever meet. I’ve had people tell me that they look forward to the holidays just to find out what she is going to send. Most Novembers, our garage looks like a scene out of Honey I Shrunk The Kids as Joyce invents a new holiday greeting. Each of these inventions takes countless hours of brainstorming, planning, experimenting, assembling, and tweaking to get it “just right”.

There was the mobile of our kids made with clear fishing line tied off. The fishing line, being so slick, would always untie until Joyce figured out to add a drop of glue to the end to keep it in place. Problem solved.

A few years ago Joyce made a lantern with pictures of our children on the outside. It took a lot of research and experimentation to make sure the cardboard comprising the lantern was sufficiently coated so as not to catch fire but still provide a cozy glow. Good to go.

And probably the most interesting of all, there was the snow globe which contained an acrylic encased photo of our daughter Kiara reaching for the stars. I remember Joyce’s frustration trying to pry the small Lucite blocks from their molds until she realized that sticking them in cold water would loosen the blocks from the molds due to the CTE mismatch between the materials. Then, these Lucite blocks were placed in baby food jars that had to have just the right mixture of water and propylene glycol to be viscous and not grow algae. Perfect.

About a year and a half ago, we were visiting Legoland in Carlsbad, CA. My kids (then 4 and 6), especially my son, have a gift for getting “sidetracked”. So, Joyce thought it would be a good idea for our kids to have our cell phone numbers conspicuously on them in case they got lost. That way, it would not depend on their memory of our cell numbers for us to be contacted by a helpful stranger if they wandered away. That’s when the idea for the “WhoTat” was born.

Joyce decided to start a business called Aware Gear that would provide safety products for young children. The first product was the WhoTat which is a temporary tattoo that is personalized with a phone number to call in case of emergency. Kids like to wear them and parents know that their kids don’t need to remember their phone numbers. Now, I’ll admit that I was personally dubious that this was needed. After all, how hard is it for a kid to remember a phone number? The problem is that most of us have several phone numbers (home, work, cell) and a scared lost child of any age can get confused and even mix the phone numbers together. That’s what my son did, mix the numbers together.

As with the other holiday greetings, this was an invention of its own. At first it seemed easy. Just buy these tattoo sheets that could be fed into a printer, design some neat tattoos, add the phone number, and print. But it wasn’t so easy. First there were moisture issues where the printing process wouldn’t work on humid days or the ink wouldn’t stick. Then the Tats were kind of sticky, so baby powder was used to remove the stickiness, but not too much so as to blur the image. It was probably 6 months before she got the process down to something that would repeatably produce a high quality product.

The second offering was a skin sticker where you could write in your own phone number or message on the fly. Again, material problems. Most recently, she is producing glow-in-the-dark skin stickers called gid-its. With Halloween coming up, and all the inherent dangers of visiting strangers while trick-or-treating, this should help kids stay safe. Once again, this has proven to be a real lesson in materials science, specifically how to get paint with glow-in-the-dark powder to adhere evenly to a non- porous acrylic surface. Who knew? Oh, and 2 days ago she told me about another invention idea and I already see the beginnings of prototypes around the house.

Since Halloween is coming around and child safety is a big concern for a lot of parents, I’d like to ask a favor … ummm … I mean offer you an opportunity. Actually, 3 opportunities.

First, as I mentioned, my wife is a creative genius and you have the opportunity to acquire some of there original work. Her products really do help to keep kids safe and are fun and you have the opportunity to get them for your kids. If you don’t have young kids, tell a friend who does. You can order them here. An if you use the checkout code ASICGUY10 you will get a 10% discount.

Second, you have an opportunity to support a good organization. In addition to the 10% discount mentioned above, Joyce will donate 10% directly to the National Center for Missing and Exploited Children. The NCMEC acts as an information clearinghouse and resource for parents, children, law enforcement agencies, schools, and communities to assist in locating missing children and to raise public awareness about ways to prevent child abduction, child sexual abuse and child pornography. John Walsh, Noreen Gosch, and others advocated establishing the center as a result of frustration stemming from a lack of resources and coordination between law enforcement and other government agencies.

Lastly, if you have gotten some value out of reading this blog over time, then here is your chance to thank me. I’d really appreciate it.

Nov 10, 2009 8:24 PMGoogle making Waves across all its Apps?from Engadget by Thomas Ricker100+ people liked this

We just received a set of screengrabs from an anonymous source giving us a glimpse at what appears to be Google's (and thus, the world's) future interface to its web applications, Gmail in particular. While we were originally tempted to ignore them, communications with the tipster would indicate genuine insider knowledge. Regardless, we can not independently confirm the authenticity of these images. Having said that, the pics demonstrate a more unified apps interface based on Google's Wave and accessible from any browser (as they are now). Specifically, we're told that "the goal is to provide a consistent experience throughout all Google Apps and blur the line between the browser and the website (e.g. drag and drop, right-click, etc.)." Something that certainly makes sense to us based on what we know about Google's tender approach to its Chrome browser and its future "lightweight" Chrome OS. If true then this "work in progress" also hints at the importance of Wave to the future of Google. Then again, it could be just one of many possible interface concepts from Google's burgeoning developer's sandbox.

Nov 10, 2009 8:24 PMExclusive: Google Has Acquired Gizmo5from TechCrunch by Michael Arrington100+ people liked this
Last month Skype was in talks to acquire VoIP startup Gizmo5. It was a perfect backup plan in case all that IP litigation didn’t work out. – Gizmo5’s SIP infrastructure could theoretically replace Skype’s proprietary P2P back end.

After the Skype settlement, though, Gizmo5’s strategic value to Skype sort of plummeted. In the meantime, Google bought them, say multiple sources with knowledge of the deal, for around $30 million in cash. The deal is done, say our sources, and will be announced shortly.

Gizmo5 is a good fit with a number of Google products. Google Talk allows voice calls between users but has no PSTN link to allow incoming or outbound calls to real phones. Gizmo5 does this well already.

And Google Voice is a great VoIP and phone identity service, but they have no endpoint for calls. Gizmo5, which by the way already integrates with Google Voice, is a soft phone end point for Google phone users. In other words, you will be able to make and receive calls to your Google Voice phone number from your computer.

This looks to me like Gizmo5 will be the glue that puts Google Voice and Google Talk together into a single product. And that product looks a lot like a Skype competitor.

Gizmo5, which was founded in April 2003, has raised $6 million to date, plus an unspecified amount from founder/CEO Michael Robertson. Prior to Gizmo5, Robertson gained notoriety with his founding of MP3.com and later MP3tunes (which has led to big music suing both the company and himself personally).

We’ve reached out to Gizmo5 and Google for comment.

Reductive Cross-Coupling
Regioselective Reductive Cross-Coupling Reactions of Unsymmetrical Alkynes (p NA)Holly A. Reichard, Martin McLaughlin, Ming Z. Chen, Glenn C. MicalizioPublished Online: Nov 24 2009 1:15AMDOI: 10.1002/ejoc.200901094

Reductive cross-coupling chemistry is emerging as a powerful strategy for bimolecular C-C bond formation. A central issue in this area of chemistry is controlling site-selectivity (regioselectivity) in the convergent coupling process. Here, we discuss the state-of-the-art with respect to controlling regioselectivity in reductive cross-coupling chemistry of alkynes. The emphasis of this review is on bond construction, not the nature of the metal employed or whether or not the coupling process proceeds in a catalytic manner.

Antioxidant Models
A Water-Soluble Cyclic Selenide with Enhanced Glutathione Peroxidase-Like Catalytic Activities (p NA)Fumio Kumakura, Beena Mishra, K. Indira Priyadarsini, Michio IwaokaPublished Online: Dec 3 2009 7:25AMDOI: 10.1002/ejoc.200901114

Water-soluble cyclic selenide 1 exhibited higher GPx-like catalytic activities than the linear selenide analog in the reaction of H2O2 with mono-, di-, and polythiol substrates. The enhanced catalytic activities can be ascribed to the cyclic structure, which elevates the HOMO energy level of 1 and makes the selenium atom more exposed to the surroundings.
