I personally started out with MSN, and I was a major MSN supporter, then I saw ALL my friends used AIM. So I made the switch, and honestly I like it a lot more.
And if you add DEADAIM to the newest AIM version, its even more amazing.
...I liked YIM, but not enough people around me use it so I ended up uninstalling.
