Do teenagers still use AIM?

I grew up in the mid 1990's with the birth of IMs via America Online's client software. Then in 1997, I and many other moved to then dubious "AOL Instnat Messanger", which were used by super geeks that didnt use AOL. Im 25 now. But in 2007, do 15, 16, and 17 year olds still use AIM? Me and many of my friend still do....but I was wondering if it was a dying trend or one for the next 50 years?
