Oh, I have a suggestion that can leverage what you are proposing for the bounties? It has to do with the Steem Power distiribution, that a lot of people are talking about. Think is if you tack an SP reward to the bounties on top of SBD reward, you are giving people more shares of the system. It solves the following 1) it works like #spreadthepower initiative, so that people who have trouble getting recognition via their content can earn SP and thus weight in other ways, while; 2) stabilizing the price a bit, by bypassing the distribution via the market; 3) meliorates the fears that people have about their inability to decide what is valuable. Oh, and another thing is it isn't possible to abuse via sybil attack! :-)

Maybe even double the bounties, or at least make them like that the Steem Power ammount to equal SBD payout. I.e. 1000 SBD + 1000 SP. Or perhaps consider paying out 1/3rd of the bounty as SP.

Right now I can't participate in the bounties due to the lack of computer, but I am really inspired by the platform and hope it succeeds. Please consider this suggestion!
