This is one of those "different strokes for different folks" sort of thing.
I tend to be a "game-hopper." I like being able to comment on multiple games within the same thread, and I don't mind reading comments from folks who are watching other games. But I guess I can see how some would find it confusing or disorienting.
If there's a single game that is particularly important and compelling, and it figures to warrant more extensive discussion, then I can see the value of single game-specific thread.
At this point I'm not in favor of having conference-specific threads between now and Sunday because there are 15 different conferences still in action, most of which will garner only sparse discussion. That would have been better when the power conferences were still in action, perhaps.
