Good idea. But who is supposed to decide which questions are serious and which ones are dumb? Or which answers are serious or dumb for that matter?
I say mix the 2 together
There definetly is a difference between serious, stupid,political, sexual, philopsophical, psycological, etc, etc, etc,. Just ask, is that not the point or purpose of this site? They say the stupid question is the one you don't ask.
I think there are plenty sections here already. If you don't appreciate the stupid ones, just scroll past them. That's what I do.
I think it would be pointless because serious questions tend to have stupid answers since there is not a reliable criteria to separate a serious question from a stupid one or a serious answer from a stupid one.
The problem with that is the people posting the stupid questions don't realize they're stupid.
