I don’t know. My main gripe with StackOverflow is question getting closed for being opinion based or not worth debating. When constant debate is actually fun and interesting. (And you don’t have to watch the threads if you don’t care.)
That does not mean that such questions never come through to reach not just an answer, but two or more trying to compete--which the voting system should be able to handel--or they are trying to mediate pretty much in unisono--which should be a comment to improve the question, or answer with a differentiated view on what the questionair got wrong and right.
That also depends on the kind of stack. The more scientific, the more rigid the rules. The more liberally academic, the more people looking to practice their rhethorics.
