Which is your most used Protocol?

For me, it always been AIM, as all my friends use it (and mostly exclusively). I've heard that MSN is more popular internationally than AIM, but I've yet to run into really anyone that uses it myself.

Any thoughts?

Windows Live Messenger for me. Fast and effective, plus all my friends use it.
