I guess this is more about where I've NOT seen edition wars, but...
One interesting thing I've noticed is that there are some people who post to multiple forums who specifically go to one forum to troll for an edition war, and then go to another forum to be reasonable. I've noticed at least one crossover where a forum member trolled ENWorld like a true master for months, while posting on rpgnet as a totally reasonable human being.
It makes me hate them ever so much more, because it proves that they're doing it just for kicks.
