I think the other problem is that Facebook makes it more acceptable to use your real name and real information. I remember the old days of the internet where you were wary of marketers and spammers and used as much fake information as was possible in order to use a website/service/whatever. Facebook definitely makes all of that easier mainly because it puts it in one place. Instead of having to do multiple things (talk to bank, phone company, visit your house, monitor all the places where you're writing), it can do just one thing: ask Facebook for all your data. Centralization and acceptability of personal information being public are the two main problems.
