I absolutely love Facebook. I use it daily. It's fun adding random AIM names to my buddy list, having Facebook tell me which ones are signed up, then it reveals their real name to me, lol.
Lol, I was just joking.
It's a great site and I made a lot of friends at my college there, with similar interests as me. I created groups there over several RPG series, like Tales, Xenogears, and many smaller series.
