This is an amusing thread. I don't mind being corrected, but I generally avoid posting crap that requires correction. My brother, on the other hand, is a bit different. He'll post whatever he wants to believe is true and states it as fact. I called him on it a couple times, so he unfriended me. We haven't communicated since.
I've considered dumping facebook, but when used correctly (like hiding the idiots), it's actually pretty nice. I have a large family and probably wouldn't even know that my niece had another kid if it weren't on FB.
