Some ideas:
- Limit the total amount of SP that can be delegated by an account to some percentage (10, 25, 30%)
- Reduce the value of delegated SP in some way (1/2, 1/3, 1/20, etc)
- Improve the discovery capabilities in Steemit.
- Adjust the payout duration to reward longer lasting content instead of just more ephemeral content.
- Compare and contrast why 'Promoted' posts seem less effective than more complicated vote bots.
- Adjust the Promoted page to improve discovery and surfacing of promoted posts
- Build out new features that mimic the community-building capabilities that causes people to drift to Discord rooms.
- Adjust payouts to better reward minnows. In many ways, the concept of a few whales acting as gatekeepers to content is pretty antithetical to Steemit's ideals. The core idea from my perspective is that hard-working and solid content creators can find the long-tail audience that supports them without the need for a dolphin or a whale to throw them an upvote or for them to buy their way into discovery.
