Good points.

I'm not so sure benefit of the doubt must be earned. More like, any participant in a discussion forum must show it when answering, and do proper research before asking anything. If all questions are good questions, there's no problem. But, as you say, they really aren't. I think poor question should be down voted with a brief explanation instead of trying to answer the "real" question. Or moved to a Frame challenge forum.

Are we trying to answer the question or to solve the problem?
