I'm on Twitter now. My username is jannispohlmann. I guess I'll be microblogging about software (Xfce!) mostly and post the personal stuff on Facebook were only my friends can read it (hopefully). Follow me if you're interested.
Edit: Ok, I'm also on identi.ca now: identi.ca profile. I'll be forwarding anything from ident.ca to twitter, so you can follow me wherever you want.
