I like facebook, it helps me keep in touch with all my mates who are at different unis. I use it alot, not to the extent that I would say I was addicted or anything, but it's a pretty helpful way of keeping in touch with people you don't see on a regular basis, but I suppose I could do that with Skype or a Phone if I ever decided not to use facebook, and as Lee said, I spent about 18 years of my life without it, so I am sure I could survive.
