Haha yea, if we talk about message boards and forums being social networking (which I'm sure they are, but just less known), I've been addicted long before I was ever on Myspace!
Oh me too. I was doing the AOL chat room thing for Xena as far back as 1996, when chat rooms were the place to be at night. I was a freshman in high school at the time, and we'd just gotten the internet at home. Then the allure of that wore off once I found the Studios USA message boards (no longer in existance) and my love affair with message boards began!
