Agreed. The social ads, creepy frictionless sharing, the history of privacy issues, the "hidden options" UX, the lack of anonymity, and the lack of support for multiple facets to our identities -- these issues all combined together made me deactivate my account.
I'm still trying it out to see if I can live without it for a year. But I'm hoping to delete it altogether.
I made it about 10 months before I caved in and recreated an account. It's so ingrained with my family and friends. But, just don't log in and cancel all the email notifications, works pretty well.
I've had friends say "oh we forgot to invite you to the party because you weren't on Facebook." I'm glad of the friends that use evite.
