I can definitely see gmaps being there i use it from time to time, but i also have no problem yelling at someone on the side of the road to tell me where im going lol.
seriously I dont see how people like facebook that much, I have a fb and most of the time i get annoyed with it cuz people post the dumbest things just so they can post. e.g. "Roman went to the gas station to buy a coke zero and is having an ok day." <- who gives a crap. I spend way more time on pinstack than facebook, well pinstack and cracked.com lol
