Increasing curation rewards should increase the number of curators so that you could earn more money with 50% thab 75%. However, i dont think it is that important and i expect people still wont give a shit. Its still more profitable to self upvote.

I expect 50/50 will only increase the amount of curational trails and auto upvoting.

This is what happens when too many nerds and not enough normal human beings congregate. But i could be wrong.
