I do not support all three of these things together. While I might be able to support higher curation rewards, I do not see this as the most important element to work on at this time and I do not want to see SteemIt, Inc's dev team pulled off of SMTs and other work that ads appeal to those outside of our community.
Curation is a large account game, it means very little to most of our users.
We had everything in this mix before and it didn't matter. minus a downvote pool. The big accounts just followed Authors they thought would be successful and upvoted them for rewards. There wasn't any curation in it the first go around either.
