"Daddy, where were you when privacy died?" "I was on hacker news commenting through facebook connect."

On the one hand, I don't have to use facebook. On the other hand, I worry about the immense asymmetry of information that facebook has about me even if I don't join. If I'm a hole in the social graph (because all my friends use it regularly to post pictures, etc. of me), it doesn't take much effort for them to fill in the data on me.
