Today I've received a following letter about my bounty question.
Here is a quote:
Please review the answers. If you feel one of them deserves your bounty, award it by clicking the bounty icon to the left of the answer. Otherwise, you might consider providing feedback in the form of comments or edits. If you don't award your bounty, the highest scored answer (with a minimum of 2 score) provided after your bounty started may be automatically awarded half the bounty amount.
The thing is this very question does not have any answers at all. May be we should send such letter only when there are such question that could be awarded?
This is not a proposal, I just want to comprehend the original position. May be there are technical limitations, or may be it is an ideological issue, and this is done intentionally - just like with vote arrows near my own questions.
