Twitter

A Twitter discussion is severely different from any other type of discussion I am used to.  Compared to a blackboard discussion, we are limited to 140 characters and have to tag our class to make sure it shows up on the feed.  If we are responding to someone's tweet, we must reference their username with the @, otherwise, no one will have any idea what we are saying or why.  On the one hand, it does encourage us to be quick and creative since we only have limited space to say what we need.  On the other hand, it is very confusing if you're not familiar with it, or if you have more to say.
In-class discussions are much more personal and in depth than a Twitter discussion, and in some cases much more helpful.  Twitter doesn't seem to be the place for discussions, but rather spontaneous or necessary declarations that don't overload the reader with information or questions.
