As long as it isn't something drastically stupid I'm for it and will influence the new landscape. And you can tell I don't think it's stupid. Compared with the change from n^2 to n, I see this as a return to some nonlinearity without making it crazy at the high end.
Now about 50/50, I see it the following way: it may not make lazy people curate, but if they are just farming they have to wrestle with the nonlinearity AND curation sniping (remember whatever leaked to others in curation in 75/25 doubles in 50/50), and will surely be making less. And this affects bid bot delegation as well. I see that as a win.
Yes your quote is true, but the truth is they actually will be getting less than they otherwise would with no changes. Make even the dumb optimizer gravitate towards behavior that is helpful, or penalize it. As I mention, a post farmer will be encouraged to consolidate their voting to expose their risk to downvotes. But the effectiveness of the system is more contingent upon people actually downvoting. That will be the real test.
