I've noticed the resurgence of the Edition War as well. Or maybe I've slipped into more problematic threads of late.
I've always found ENWorld pro-
4E. It seems every thread has an anti-
3E backhanded comment such as "Before
4E came along and saved me from
3E,..." This used to really bother me, but now I laugh. Still, it gets tiring to see the same names making the same references. I generally stay to threads I feel aren't going to go that direction, but sometimes curiosity gets the better me.
As a result, I spend much more time at Paizo. Yes, there is an edition war there too but it leans more my direction.
