Ken recently left for the same reason
He recently popped in for the Babble 20th anniversary and touched on this- if you scroll down you'll see the thread. But anyway, like I told him, it'd be great to have you post more often but I totally understand and support folks leaving Babble to cut down on their screen time.
But as others have mentioned, there hasn't been a true flamewar on Babble in forever and whatever shit talking does take place is brief and extremely mild. Barely any troll posts either. So it's not the Babble you remember and probably have negative associations with.
