I have all of the IM's because all of my friends can't agree on one IM, but I mostly use AOL IM even though I hate AOL, but that seems to be where most people I communicate regularly with are using. You CAN use AOLIM without being on AOL.
It would be nice to have chat ability here so if there are a lot of folks on, we can all jump into chat, or maybe even schedule some regular chat times.
