I agree, I hate the voting bots on Steem. But it's like buying Twitter followers, it won't go away.
Minnows and Dolphins are slowly getting more support from initiatives like @sndbox and @minnowsupport. These initiatives help surface out young authors' content.
Also Steemit's curation model itself could be flawed because of pages like Trending. Another Steem front-end service like Busy or insert Steem project here could use a different curation model which could rotate out new content.
