I have a suggestion for combating the 0% accept rate some users have, and continue to ask crappy questions.
Perhaps if they get to 10 questions with 0% accept rate (using the existing metric), could we hit them with a please accept an answer on a previous question to ask your new question.
I know SO now have the asking questions advice page if they have a low rep, but I was wondering if forcing them to accept one would help - maybe they just don't know how to accept, and if they were forced to accept one, then they would know how to from then on in.
I know SO has always been about freedom of asking questions, but I think after having asked 10 questions you need to give something back (by awarding rep, at least). It may clear up some noise at least.
