I think reducing IG happenins talks at OOG will help, ofcourse there will be some chatting and speculating at IRC/skype/name any ohter instant message system, but those are not that public and arguing at example IRC doesnt last like 2 months... those are over in few minutse to hour.
Wiki had that diffrence back the days when there was those news papers, that those were kind of in game. Those were public knowledge. You wrote page at news paper was similar as you would send message to whole continent, or even whole world.
Ofcourse those discussions over the topics heated to flamewars too...
