This is insufficiently meta. Consider that this very simple and vague payout scheme is probably not optimal for encouraging good bounty suggestions. I suggest going one level up and putting out a bounty for the optimal incentive structure of bounty bounties. A bounty bounty bounty, if you will.
(This is mostly a joke, but I’m not adverse to getting paid if you actually decide to do it)
Edit: now that I’ve thought about it more, something in this space is probably worthwhile. A “bounty bounty bounty” is, funnily enough, both too specific and too abstract. However, a general “bounty on optimal bounty schemes” may be very valuable. A detailed investigation into the optimal bounty payouts for different goals, how best to split bounties among multiple participants, how best to score proposals, etc are all important questions for bounty construction. A bounty to answer such questions makes sense.
