I deactivated my account over a year ago. Facebook will not delete your account, deactivate is the best you can do. Interestingly I went to a Facebook event at their headquarters and when I signed in, there was my profile picture staring back at me. I thought pulling it out of my deactivated account was in poor taste.

Anyway, I can say I'm happier without it. I'm now seriously considering deactivating my Twitter account. Twitter really will delete your account after I believe 30 days of it being deactivated.
