"Nike has discovered that there's a magic number for a Nike+ user: five. If someone uploads only a couple of runs to the site, they might just be trying it out. But once they hit five runs, they're massively more likely to keep running and uploading data. At five runs, they've gotten hooked on what their data tells them about themselves."

"TweetPsych uses two linguistic analysis algorithms (RID and LIWC) to build a psychological profile of a person based on the content of their tweets." Interesting analysis. What I don't like is that it was built by a "Social Media Scientist" who is probably using the results to find better ways to sell things.
"This Friday, June 12, TV stations nationwide will cease broadcasting analog signals and switch to digital-only broadcasts...Starting Friday, I can no longer get TV on the radio." Didn't think of this, what a bummer. I've used this trick occasionally too, especially when the power goes out. [via MeFi]
"...new kinds of lock-in in the era of [cloud computing] will be owning a namespace." That's Chris Messina paraphrasing Tim O'Reilly on Web 2.0 in general, applied to Facebook's new vanity URL feature specifically.
"I tried to alternate the charming children's covers with the creepy modernist covers, but I soon lost the ability to tell one type from the other." Excellent collection of early 20th century graphic design in Japan. Be sure to check out the previous post with book covers too.
Google's take on YSlow--Yahoo's excellent website performance analyzer. Not as polished as YSlow, but looks promising and includes some analysis that YSlow doesn't cover such as CSS efficiency and image compression.
"I'd argue that attention is an important part of the status metric; but I don't think more attention always translates to more status..." Interesting thoughts about why people contribute on the Web. [via anil]
