curation rewards are bad and serve no good purpose at all
well, maybe author rewards are also evil then ? )
Since people would keep voting for posts even wuthout curation rewards, I think the same would apply to authors too, they will keep posting even without rewards )
Curation rewards create a lot of bad incentives ( mainly they encourage bot/fake voting), author rewards don't.
That could be disputed. For example, authors with a following milking it but posting crap because they know their followers often upvote regardless of quality or have low standards.
