DONT give facebook your correct name and birthday.
Facebook REQUIRES you put a date there so I chose April Fools Day 1906------as far back as they'll allow.
Every year I get a half dozen or so happy birthdays on facebook on April 1.
I convinced my younger son to use his mom's maiden name on Facebook so if he ever goes looking for a SERIOUS job or graduate school application they don't look him up and see all the goofball stuff he posts with his frat buddies and various girlfriends.
Everyone worries about Big Brother watching you? Not that hard to do, huh?
