Google goes Facebook, AIM goes Twitter

AIM has added a new "lifestream" that publicizes your status changes, twitter-style, and is public by default. Apparently, according to antimony, they also make it visible to other people when you "friend" them, which I think means add to your buddy list. If you want to make your "lifestream" not public, go to http://lifestream.aim.com/settings and log in and change your settings. I don't know if there's a way to restore the former ability to add people to your buddy list privately.
