Ask HN: Would you pay developers to fix open source bugs?

I could see it working well for GitHub. You would submit a bug to some sort of "bug board" with a link to the repository and attach a reward (you choose the amount of money). Other developers could then choose to fix a bug and maybe the developer who finishes it first gets the prize? However this could lead to crappy code and there would be wasted developer time (developers who don't finish first).

There could be many other ways to award the prize but I'm just curious if you would ever use a service like this?
