This week I made a twitter acount. I really have not had a chance to use it but I see how you could use it for a class. You could post reminders or little tid-bits about your subject area. You could have all of the students look at your tweets and discribe what they have learned. It is just another good way to give your students the oppritunity to learn. I think that this could be helpful some time in the future for me as a teacher.
