FaceBook Just Wasn't for Me

I like Posterous much better. 

And it felt really powerful to unfriend 30 people at once with 2 clicks.  Mwuuuuhahaha! 

But seriously, why did I deactivate Facebook?  Google's autofriending me across the internet with their recent Buzz release really made me think.  If Google (who usually does no evil) is making me more public than I want to be, then what the f#%$ am I doing on FaceBook?
