I would like to revive this feature request: Sort questions by user reputation
On stack overflow, I like to browse questions tagged "matlab" and be helpful when I can. Unfortunately, this tag seems to attract an inordinate number of "how do I solve this specific homework question" , "here's a page of incomprehensible code -- why doesn't it work" , and "how do I do computer vision -- please advise" for every real question asked. These questions are typically asked by "user12345" types with single digit reputations.
The downvote system doesn't really work well here; it's not worth it to spend time downvoting questions from users who clearly have no investment in their own reputations.
The number of spam questions makes it hard to identify legitimate questions. Would it be possible to set an option to suppress questions from users with a reputation below a certain threshold? I recognize this might be seen as discouraging new members from joining the site and seeking help, but the option would be turned off by default anyone who wants to help out and sort through junk questions to find good ones from brand new users would just leave it off.
EDIT
Alternately, would it be possible to ignore questions from users who have not been members for at least one week. I think it's fairly naive to think you can't at all judge the quality of a question based on the person asking the question.
