I don't get it. What is the point of Twitter, exactly? Yeah, I have read about it and think I get it conceptually, but practically... what do you use this thing for? How does it make you more productive or happier? Serious question. I would like to be interested in it and want to know how it is useful, because it doesnt appear (to me) to extend any existing technology. Seems to do the same thing that an away message does on Trillian/ICQ/IM apps.
