Well, having all the rivalies confined to one forum might prevent them from spilling all over the place. And having no moderators would end the "moderator X went too far closing / editing this thread" posts in this forum.
I have no real issues with the current "moderation protocols" in place on FlyerTalk. My only issue is that a few people getting frisky can shut down a thread that had good dialogue going, but it's easy enough to keep opening new ones to try and keep the positive conversations going. And it keeps folks on their toes as they have to bounce from closed thread to closed thread to follow along.
