It's been 3 weeks so far[1] and it's amazing how after the first day Facebook started sending me two emails per day, along the lines of "you are missing important posts from your friends" and "you have 8 pending notifications". It instantly reminded me of Zynga's tactics to try to suck you into a game and paying for content.
[1] I made ONE exception- my close friend was missing for 24 hrs, left his wallet and phone at home, his parents freaked out so I reached out to all his friends on Facebook. This tells me I only need one feature Facebook has to offer - access to my own social network. Somehow we conditioned ourselves to only share Facebook information but not phone numbers or emails or any other means of communication. If Facebook suddenly went away I would lose 3/4 of my contacts. That's a scary thought.
