Yes, I agree I think curators would or perhaps should be okay with a 10% loss on curation. The bigger whales should be able to easily absorb that kind of loss. Of course they could make it up if they increase their blog output by just one extra post a week.
I'm pleased you agree with the suggestion of a 60/40 reward ratio in favour of the authors. I wonder if there is a majority consensus within the community who favour 60/40? I am trying to gauge it.
