The problem with that is that curation doesn't do anything for mass adoption. By its nature only major stakeholders can play that game. Everyone can get author rewards, non bloggers included. There is no reason why only bloggers can receive author rewards, people get them for selfies, videos, anything.

Monetizing dapps via curation rewards makes no sense as a model. The dapp in that case is basically just a vessel for voting. Success has little to do with the quality or popularity of the dapp and is just a method to monetize delegated influence.
