What about this very thread?
It may be 'somebody else's fault' but surely we know from the grammar school that adults never really cared who started the fight - they just want the fight to stop. Everyone is equally guilty here. Returning the punches is just as much of the problem as throwing the first punch.
I'm sorry but I still fail to see the logic here. As I've already pointed out, spills does occur and that would be just more work for the moderators. Humans are an emotive lot- they want to get the last word and whatnots. I don't imagine that anyone has never been tempted to scathe the other and look good in own eyes. Enacting a wall won't stop the hurling over the wall. It's no different from those silly sections in restaurants - non smokers on one side, smokers on the other side, yet the smoke perpetuate the whole room. We're either a smoking establishment or not at all. Whichever we may be, is entirely up to Jon and those he delegated.
Even then, that completely miss the point. The point here is there is no reason or need to resort to cheap shots to make points, but it would be quite challenging to have a intelligent discussion if the thread get flooded with non sequiturs, irrelevant generalizations, and small-minded nitpicking. This is the real reason why I don't participate in most of WC threads and many other posters do likewise. When a thread does actually raise to the level, I do and I suspect the same group of poster does so. So in a way, the wall is already there but it certainly isn't going to stop somebody from rising to the bait or getting offended. Even worse, it's not going stop anybody from prolonging the drivel and clogging up the 'View the New Posts', crowding out more interesting threads or even technical threads for which the forums was presumably created - to help others.
Sometime I can't but help wonder what new people coming to the forums may think of the watercooler when they first visit and what effects it would have on the forums as whole. Seem to me we would want to attract more bright people with talents and potential to help others and not put up an open invitation for even more trolls and driving away talented people or even novices looking for help. But that's just my imagination and that's entirely up to Jon to decide how he wants to run the forums.
