I recently asked a relatively well received question which was not getting any answers. I placed a bounty in order to get some more attention.
Finally I received one answer within the bounty period. However I did not feel the answer was sufficient to claim the bounty, it was relatively generic and the poster themselves implied some of it might "seem like nit-picks".
Although the answer was useful and I upvoted, I decided I wouldn't give it the bounty, to convey the message that I was after an answer which went into some more specific-depth.
I feel bad now, because a second upvote meant the answer automatically got half the bounty, but I had made the decision not to award it. I could've just as well given all the bounty to the answer.
What should I have done here? Is it fair not to award the full bounty if an answer is deemed by the community (through voting) to be worthy of receiving it?
