Twitter's Business Model? Well, Ummmm...

"When the earth shook in Los Angeles last week, the first reports didn't come from traditional media outlets, but from Twitter, the "micro-blogging" service where users can send short, instant status updates to their friends via e-mail and mobile phone. Ten minutes before the Associated Press reported news of the tremor, a Twitter user named Caroline (Vixy) posted a simple update: "Earthquake."

Blogs and news sites buzzed the next day about how Twitter had ushered in a new era of communication. Such proclamations would have most internet entrepreneurs seeing dollar signs. But not Biz Stone, who insists Twitter's mission is simply to provide a useful, robust service and let the dollars follow later."
