There is a feature that gives the bounty amount to any answer with 2 votes. (If the person who issues the bounty does not choose an answer.) Which is a good feature.
My suggestion would be to have a corresponding bounty-refunder.
If the question itself gets 2 or more votes, but no answer is chosen by the person issuing the bounty or the auto-bounty-picker does not kick in....then the person who issued the bounty should get all or some credit back.
My questions seemed to be a decent one (4 votes). But no answer was up-voted. (Or detailed enough IMHO to award the bounty.)
Maybe I'm not seeing something, if so, let me know.
I know this has been discussed before:
I'm not complaining about not getting my points back. (I understand the current policy and accept it.)
If no answers meet these criteria, the bounty ends without it being awarded to any answer, and is not refunded to the bounty starter.
I'm suggesting a new consideration when the "Question got UP-Voted", but no answers were bounty-awarding-worth answers. Or maybe a partial refund to prevent bounty mis-use.
But sometimes someone asks a decent question, and there wasn't any bounty-awarding-worth answers.
