Occasionally I see questions with plenty of upvotes, but without interesting answers yet. One could assume that most of the upvoters would be interested in an answer, yet there are usually only <50% as many stars as upvotes. That makes me believe that most people don't even know about this feature. Perhaps it would be worth to display a small explanation next to the star if a highly upvoted does not have a good answer yet.
Edit: I misunderstood something, please ignore.
