Curation has to remain impartial regarding if the project is receiving extra rewards from the authors or not.
I completely agree to your thoughts, however, unrelated to all this, I think, we need a better way to incentivize people, without having them to write big posts. Like playing a game, or even a lucky draw every day to randomly choose few, to take this to masses. Hopefully all the games being developed will take us in that direction, but Spinerlands did no good even after being so popular. So we need to think, how we can have a good use case to attract the mass.
