Finally, I'd like to say that Tom encouraged his class to tweet during class. I think that is fantastic. The tweet stream is like publicly available course notes for the class we did yesterday. Every time I talk to a class full of students I am going to call out a hashtag at the start of class and encourage tweeting.

Tweeting in class! Counterintuitive though it may be, we endorse the approach, with some provisos. No at-messaging celebrities; Tweets about technical mishaps with overhead projectors are to be kept to a minimum; no tittering.
