I see the entire "content reward" pool as a potential "Steem ecosystem contribution" fund.
Content is just one type of contribution that I believe we have way to much of.
We could redirect all flagged reward to the fund account and it'd increase benefit to down-voting stakeholder. Currently if one believe that more than 50% of reward is miss-allocated down-voting it just moves around the reward to almost equally undeserving content.
From what I understand we need a monetary incentive and a governance system to decide and implement a better inflation allocation system. None of the dozens of suggestions made in the past were ever discussed or considered seriously due to a lack of someone other than Steemit being able to implement it and their stubborn focus on the wrong priorities like SMT .
Taking an arbitrary % of inflation at this stage is premature when we could be using the same stake weighted voting system we're used to to decide individually how much of the global reward should go to an accumulation account with a more sophisticated management.
I actually like that.
Smooth actually proposed using the proposal system as a means for allocating the inflation, and I thought it was a great idea (search down and you can find it). But I think it's too big a step right now; I think it should be done after we have the proposal system operating.
