For me, Twitter shows potential of contributing to the "third places" of online life. The informal coffee shop where you're free to overhear conversations and join in when you want... but just as free to keep reading your book. No harm in sharing what's on your mind, no expectation to reply to what other people say. It helps that right now, it has a self-selected group of people who are pretty open-minded and have something interesting to say (but the narrowness of this self-selection will grow weaker with popularity).
I just started using it... I'd like it a lot more if Twitterific didn't keep automatically popping itself into the foreground with another "Twitter Error". Incessantly drives me nuts.
