Are you Twittering?

I've been using Twitter for a while now and must admit that it has stuck in a way many social tools have failed to for me. Part of the reason, I suspect, is that it's very low effort. But more to the point, many of by online buddies are using the service as well and that makes it a very convenient way to keep up to date on what they're doing.

Yes, there's an inevitable noise level inherent in this sort of thing. And the volume has gone up (way up) since Scoble, Pirillo, and Rubel decided that Twitter was cool. But all in all, there's little not to like and the conversations are often quite interesting.

While reading today, I see that Rubel has started a new theme: claiming your Twitter page on Technorati. I'm interested in seeing how this ends up working.

UPDATE: Bren has a great guide to Twitter at the Slacker Manager blog.
