I don't like facebook either and am a rarity in my workplace as I don't have an account. When I was on it, I used toget jealous. Practically all the girls I went to school with are married, with kids and great jobs. I found it hard so for my own sake, left the site.
Most people I know are addicted. My boss is on facebook all the time and I find that really weird to be honest and a waste of real life.
