I was a big fan of AOL chat while in 1999 time, later i don't know why , i left.
Some days before, found an interesting article on AOL's new Open AIM .
read more on http://dev.aol.com/aim.
AOL published its protocol and inviting developers.
Now my question is where all a developer need to concentrate - XMPP, SIMPLE, AIM or some more as they get published.
A simple 2.0 dilemma :-)
