Consider this question on http://stackoverflow.com/questions/1216943/how-to-run-debug-multiple-web-application-projects-with-in-the-same-solution. I put out a 200 bounty on the question, but did not get an answer from anyone other than myself that worked.
In fact, my answer is also the highest up-voted on it at this point. I know that allowing OP's to retract a bounty can be a slippery slope, in fact I think that once the bounty is put up it should stay up. But why not allow the OP to answer their own questions with a bounty and reward it to them if they receive the same up-votes as others?
Yes, I am fully aware that bounty's are a risk. People will use them for numerous reasons such as trying to draw extra attention to their issues. However, in my specific question, the only valid answer is the one that I gave. Had it been anyone else's question, I would have received the bounty, but since it was my own I did not.
Interesting Voting Patterns... all mine downvoted on SO numerous times and the others up-voted? That is some good honest overflowing if you ask me!
And people who do this complain about serial down voting? Hypocrite!
