It seems to come in waves: new members joining AN and using their own names as user names and their photos as avatars. Although no one truly believes that the internet is anonymous anymore, there are some very good reasons not to be totally obvious, either. AN is a very good place to come to ask questions -- especially questions you don't want to run by the crusty old bats on your unit, or to vent about your professors or bosses, or fellow students or colleagues, your patients or your family. Being instantly recognizable is not a good thing.
