your proposal is interesting and i see upside where it appears to encourage concious voting, while (as you explain) still maintaining staking and posting well rewarded. up-voting may not only be a philantropic act rather -indirectly- serving the blurt-community with conciousness (whether artificial or human - that is for another discussion?). this in turn by association serves all of humanity, returning these intangible benefits to the up-voter (curator) as well. nice feedback loop u have going there! to be up-blurted! Downsides anyone?
