I don't think you can have too many content creators. Some are crap, yes, and those should maybe get downvotes. And who is interested in creating attractive content? Some might do it out of idealism. Some might get lucky and get a lot of upvotes from large accounts. But smaller accounts will mostly find it useless, and remember they are not just content creators but also readers/viewers. People who get pushed out will create negative marketing outside the Steemit platform, decreasing the attraction of the platform to new users.
The none lineair reward curve makes it so that most upvote posts that have large payouts. It has got nothing to do with the quality of the post. Most know that the biggest whales are sharing votes between each other. This further attracts smaller players to vote for them to get a higher payout. All in all I don't see much good in the latest changes unfortunately.
