I believe its the latter. because people still use their real name on FB. people can change their names - which happens. but most of the time Im seeing people use their real name and comment on news stories and other peoples posts/comments. like I said using their real name. which doesn't make it anonymous anymore like we used to be. and many sites opt to use facebook as a login to comment on anything from news articles to blogs and that makes us even less anonymous. where we could use sobriquets and psuedonyms we now have our real name. so what are people hiding? not even our face anymore with avatars next to the facebook login.

good point though. very good point.
