I agree, the problem (as I see it) HF19 tried two things at ones:
- Voting Power x4 and number of votes x0.25
- From exponential to liniar rewards
They should have done one before the other, so they could monitor the behavior of voting / curating better!
But now we're here, so I guess the best way forward is indeed changing the voting to 20 votes and reduce the Voting Power to 50%.
