This semi-scholarly article discusses the sort of anarchaic society that D2 life on B.net is, and what sort of lessons that can teach us about real life, and how it would be lived with a similar lack of constraints on personal behavior.
This article has very little to do with the game itself and it's got lots of words, some of them quite long, so rate how likely you are to read/enjoy it by your tolerance for such things, and proceed accordingly. (I.E. don't start on it, give up, and then advertise your short attention span by whining about how it was "boring." On second thought, what the hell, do so if you want, it'll give the rest of us something to talk about. It's not like anyone ever reads the intros I type on these guest article forum posts anyway.)
