Like, if I had magic? If I don't actually have to come up with methods for them it would be:
1. Replace the curation system with a system that does what it was supposed to in the whitepaper: encourage users to discover undervalued content. What curation currently does is encourage users to be the first to vote on content everyone already knows will be valued, which is not really useful in any way.
2. Replace the flagging system with one that doesn't take upvoting power and is based on a user's experience and standing within the platform. Essentially distribute policing power based on who has been here contributing the longest, rather than purely on stake, and don't have it limit those users' ability to reward.
3. Cause Steem Inc. to see the value of curation and retention entrepreneurship in the same way that they see the value of dApps. dApps are important, but building and empowering the user base is also important.
