About the Counter Strike reference... people behave like that in normal life too, not just in-game. Did you suddenly forget all the trash-talking and bullying in school that kids not good at sport or some other activity were receiving?
As a CS player that was spending 10 hours a day practicing the damn several maps over and over and over and over and over again, and playing many, many, many, many, many matches both online and locally, can tell you that the behaviour of people that act like idiots in-game doesn't differ from the behaviour they have while they're not playing.
I agree with one point thought, that once the masses get their hands on something, they ruin everything. Part of that has to do with the fact that the people who made a particular community good are now trying not to be a part of it (because they don't like the retard-ness and low-IQ way of behaving of new members, aka, the masses that joined just because the community is now cool) or just simply left.
Call me an idiot, but I am actually a supporter of the Internet ID stuff... at least the concepts of it, that a user will be unique and cannot mask behind nicknames spamming crap and all, and not worry a single second about the decision he / she makes.
