Legal Commentary

Many of us already use a variety of electronic resources in the classroom, but what about using Twitter?  Personally, I think it might be useful for some purposes, but I can't imagine it replacing TWEN or basic e-mail. It could create interesting opportunities for faculty and students from a variety of law schools to communicate with each other, and the 140-character limit would make reading go quickly (and encourage tweeters to get to the point). There are certainly pros and cons to consider. If you're already using it, how is it working? If you're not using it, would you consider it?
