I think this is genius.
Call me naive but this is a really nice idea. Reminds me of flattr except it's automated. The idea of having bounties to various project issues and setting up a commit/pull-request payout could be a real incentive for a lot of people to contribute to actual open source software.
Bitcoin is just the icing, makes this really well integrated and anonymous too. I can't wait to see where this project leads us to. Maybe an actually fully decentralized open source employment career?
