Uses for Twitter?

For anyone unfamiliar with the latest trends in technology, “Twitterers” send and receive short messages, called “tweets,” on Twitter’s Web site, with instant messaging software, or with mobile phones. Unlike most text messages, tweets — usually in answer to Twitter’s prompt, “What are you doing?” — are routed among networks of friends.

Like a lot of people, my first reaction was – whoa, way too much information. Just a lot of people sharing the mundane details of their lives. But I just kept hearing more and more about it and so many people saying how great it is.
Well, I’m still not sure what to think. But I did just see a post over at What I Learned Today… that convinced me of one thing that Twitter might be good for – keeping up with people at conferences. Anyone else care to share work-related ways in which they use Twitter?
