why not a slider or setting for content creators to set what they are offering curators?
the platform will find its balancewith the give and take between the two groups in order for each to grow. When a content creator sets their rate too high in relation to the quality of their work, the curators wont be upvoting and the creator will need to rethink their rate.
That's an order of magnitude more complex from a technical perspective.
It would also require supporting development from every front-end and voting service running on Steem.
You can already do this without too much trouble as long as the number is more than 25%. If you removed mandatory curation from the blockchain side I could spin up the back end of user-selected curation in a day or two. Somebody else would have to do the interface.
it is.. not impossible though. It happens elsewhere .. Choon comes to mind.
