Note: This might be a terrible idea.
Sometimes a question gets asked and quickly receives three or more answers. And sometimes at least one of these answers actually answers the question, but none of the answers gets upvoted. Such a question quickly falls of the front-page and lives in the "unanswereds" section, even though it has been answered. Every once in a while, the Community user will bump these questions back to the front page.
I was wondering whether it might be a good idea to have a new review queue: the "Should this answer be upvoted?" review queue. Or perhaps we should call it a "High quality posts queue", with the goal to identify high quality posts [as opposed to the low-quality queue which tries to identify low quality posts].
In such a queue, posts from unanswered questions would appear, and users would decide whether or not they are worth upvoting.
It is a natural question to figure out which posts should appear in such a queue. Perhaps one would begin with questions which 1. have non-negative vote total, 2. are unanswered, 3. have at least 3 non-downvoted answers, and 4. are at least 3 months old.
Or perhaps some other criteria --- this is just a thought. Some experimentation would be necessary.
What are some potential benefits from such a queue? Some good posts which are otherwise unrewarded might get some positive feedback, which seems like a good thing.
But I admit that I have a particular problem that this would help alleviate. On Math.SE, I sometimes browse unanswered questions to find something interesting to think about [especially while waiting for my students to show up to my office hours]. And frequently I'll find something interesting and later answer it. So I treasure a well-maintained unanswered question section.
Unfortunately, in many topics there are thousands of questions in the "unanswered question" sections which actually are answered, often multiple times --- except that none have upvotes. This pollutes the unanswered tab and makes it much harder for me to find interesting actually-unanswered content. So instead I find myself upvoting content instead of answering content [of course, that's fine --- it just happens to not be what I was after].
There are some potential pitfalls to such a proposal as well. In particular, there always seems to be a few "robo-reviewers" who seem to ignore the actual task of the review topic at hand and instead want to "review" as many different posts as possible [perhaps for the associated badges? I don't actually know their intentions]. It also seems possible that there are many topics that any given reviewer wouldn't be knowledgeable or capable enough to typically assign upvotes or downvotes.
Perhaps one way to respond to both of these would be to not allow direct upvotes from the reviewing page, but instead to have a "Mark as high quality" button. Then if X percentage of Y reviewers marked a post as high quality, then the Community user gives it an upvote... or something like that.
