Twitter

So I'm on Twitter now. I initially didn't see the appeal of it, but I found that I can follow news, sports (all of my favorite pro cyclists, for instance), friends, and LOLcats all on one page. Now of course I'm trying to find pedagogical uses for it. I was thinking perhaps of using it to post homework assignments and tips--perhaps creating a different account for each class, or one generic "Professor Berry" account.

Do any of you use Twitter? For pedagogical applications? For vaguely pedagogical applications?

BTW, if you want to follow me, I'm (not surprisingly) ttutheory.
