Despite my better judgement I now have a Twitter account. You can follow my wacky hijinks at http://twitter.com/pablotron.
I've also written a basic Jabber/Twitter relay called Joggle. I'm hoping to release it later this week. If you'd like to try Joggle now, you can grab it from the mercurial repository (you'll need Ruby, a spare Jabber account, and a few minutes to glance over the README file).
