While I'm pro 50/50, I also prefer the downvote pool to be separately delegatable, but that's more about balancing dev costs.
I was strongly in favor of most of the SPS funding to come from vesting rather than author/curation. It's strange to me that people are pushing for it to come from author/curation this hard when vesting interest does virtually nothing.
10% for SPS seems a little high for something whose rules are quite unproven and may be quite exploitable in practice (not looked into it personally). I would have started it at 5-7% and cranked it up the next HF if the rules were solid.
Could you at least bring up SPS funding at least partially coming from vesting interest rather than author curation again with the witnesses? I know you and tim are open to this. Seems weird to attempt to fix the rewards economy while simultaneously nerfing it further when we can get it funded elsewhere with hopefully little dissent. Who's truly fighting tooth and nail for the vesting interest?
