However, because everyone uses MSN, MSN wins.
Have you ever heard of an app called Adium? Probably not.

I voted for AIM because the protocol is pretty good. At least as far as file transfers go, which is mostly why I ever use it! I chat on IRC more than any of these, but I guess that doesn't count as IM.

The only native IM program I have installed is Skype. Trillian handles everything else (irc isn't IM remember!) I use adium on osx unless ichat opens for some reason or I want to webcam
