I'm on Facebook, probably more than I should be. Have got in touch with a few people I wish I had never lost contact with. Also had friend requests from people at school who treat me like a right cunt. Normally just ignore them, can't be arsed with forgetful bullshit they come up with.

Depends how you use it really, I mainly keep in touch with mates at home as I work away and obviously the wife. I do need to cut back on my Facebook pool usage, its slowly taking over my life!
