Twitter is a tool for "micro-blogging" or posting very short updates, comments or thoughts. In fact, since Twitter was designed to be very compatible with mobile phones through text messages, each update is limited to 140 characters. Truly, a micro-blog. Another way to think of Twitter is like a cross between instant messaging (IM) and a chat room, because it is an open forum, but you restrict it to the people with which you connect.
