That, among other things, is why the worst part of any multiplayer game will probably be its players.
I absolutely love how A.F. Kay is done in the dungeon run: you could almost hate this character, since it’s a fine, lifelike parody of whatever dimwit, boob or moron you could have in your ‘friends’ list. 
Or, come to think of it, the whole bunch of idiots by Tirion’s side in the Icecrown prologue depicts none others than the players.
I’ve said it once, and I guess I could repeat it:
These forums do seem a bit special, though. Sometimes I think that a prison full of recidivists, convicted for the heaviest of crimes, would appear like a civilised, cultured and upstanding mini-society in comparison to this particular… community, let alone things such as basic literacy and reading skills, some common sense and logic or even the most rudimentary of manners. Every uncooth boor has an OPINION and a great penchant for swaggering, though.
There is a rational explanation for it, however: you mostly notice those who practically live on these forums and are dysfunctional in some way, e.g. have mental issues, abuse substances and so on, while actually decent people are ‘lurking’. Not to sound narcissistic, but lemme quote myself again to avoid yet another repetition:
In this light, the passage above is probably more relevant to the more ‘hard-core’ and… vocal part and obviously not to any random ordinary guy who just wanted to report some bug, ask a normal question or such.
