I've also joined Twitter. I would rather have joined Jaiku or Pownce, as I like the look of them better, but both are currently closed to new members, and I couldn't be bothered to wait. I may try both once they are opened to new members. I like the features of Pownce, but Jaiku is now owned by Google and so it'll probably be linked into some other aspects of Google that I already use, such as Orkut. For the moment, I'm going to see what Twitter is like - I have a suspicion that it's just like the status updates from Facebook, so I may find it redundant.
I've added links to my Twitter profile and my MySpace (as I've neglected to do that to date). Feel free to drop in on me!
