I seriously did not understand why everyone freaked out. It's funny but the same people complaining about privacy and FB are the same people posting trillions of photos with no privacy settings; writing personal messages on people's walls; and hanging around on FB Chat all day long. If they were really paranoid about their privacy, they'd be a bit more discreet -- and would probably try to communicate more by video chat (the Video Chat Rounds app or the like). Lesson? People are morons.
