I recently caught the micro-blogging bug. Strange to do it now, with Twitter suspending its IM interface, and the routine appearance of its unlikely hero, the fail whale. I guess it started with Facebook updates, and then I heard about the Laconica distributed open µblog system via FLOSS Weekly. It's free software, anyone can run a messaging server, and different servers can interact.
The two biggest servers in North America seem to be identi.ca and the TWiT Army. The paramilitary theme of the latter is cute in its way, but I decided it wasn't for me. So I defected to the north and became identi.ca/chrisleague. For now, this is synced to Facebook and twitter.com/chrisleague.
And if you've got no other choice
You know you can follow my voice
Through the dark turns and noise
Of this wicked little town.
