Top five reasons to exit the facebook world forever:
1. Your "friends" regularly post such interesting tidbits as "Gee it's cold, I'm going to put on my coat today".
2. You, just once, got this scintillating comment out of the blue: "...whatever"
3. You are getting more really dumb political messages
4. You are getting even dumber medical advice
5. You begin to wonder why you ever liked those people
