But you would still stick to curation rewards to encourage voting, right?
Yep. If this happened I would introduce 50/50 and free flags to encourage it even more. It closes many gaps in the system and helps mitigate the feelings of loss. A staked/invested user is able to affect the view of the platform as well as earn at the same time while the posters are able to earn in an environment with much more visibility. It should eventually see more cream rise to the top.
