Yes, if the community wasn't mostly sycophants of stinc, et al, that might be a good way to do it.
Not many contrarians are gonna make the popularity lists and leaving them unrewarded skews the effort towards brown nosers and feel gooders negating the contributions that keep us from inbreeding.
How do you propose to rank curators?
ROI?
Really?
Without dissent it is all a circle jerk by conformists, imo.
Not rewarding those who are unpopular, and contrarian, guarantees that the circle inbreeds and only gets smaller.
Which will be very popular among the sycophants. 0.o
Remember the primary goal is attenuating abuse of the inflation by the handful of powerful accounts. I think positive curation can be structured in such a way that all points of view can be accommodated and nurtured. It requires a significant scaling up and enhancement of current efforts.
