Existing GitHub bounty bots have been doing a great job at incentivising people to contribute to open source! But what they don’t do is encourage people to continue contributing.
Colony has a bounty-like task system, but with the added feature of reputation. What if as well as (or instead of) earning a payout for completing a PR, you also get reputation? Then this gives you rights to make decisions and control project funds proportional to what you contribute.
Another way of looking at it is that this bot sets up GitHub as a UI for the Colony Network contracts.
