AOL confused...?
AOL seems to be going multiple directions without much clue. They are on the verge of launching a service capable of using/talking to Jabber. At the same time, we know that they use SIP for their VoIP services. So I can't help but wonder, which direction would their IM protocol go. SIMPLE would be an obvious choice, but with Jabber in the fray, XMPP just stuck its head into the picture.
