John Gabriel's greater internet fuckwad theory is a joke about people playing video games online, it's not really relevant to the general internet.
While chatroulette arguably offers anonymity but the very instant a website requires registration it's not anonymity anymore, it's pseudonymity, a totally different thing.

If you look at the famous example of the month of eternal september [1], the problem at hand showed a totally different picture, an artificially high number of newcomers overcharging the capacity of the community to properly teach them how to behave [2].

Then again if you look at facebook itself you'll find more than the regular share of inane bs and bad behaviour.
