Twitter

Okay so twitter it seems alright of a program i just do not see what all of the hype is about it.  To me it just isn't that great of a program.  Anyway how would I use twitter to teach my students in the future well I could have them follow me and on a separate account just for teaching and post reminders to them about homework assignments and tests or quizzes in the near future.  It would be the worst thing ever to make for the reasons of teaching and I see as to how it can and most likely will be useful in the future.
