I think we'll see Steem evolve with other use-cases and interfaces that allow this kind of interaction. It'd be democraticizing this industry and giving a voice to those that otherwise don't have one.. which is what crypto is all about.
I think that the idea behind Steem delegation is, in theory, achieving what you mean. If I have loads of SP and think a writer has done a great job, I'll upvote them (like I just did with this comment) and you get some change and exposure.
Crowdsourcing it and decentralizing it may be worthwhile ideas to look into. . like a community review panel with votes for some sample content?
Yeah and you could even add SMT's into the mix. Do something like steemhunt is doing and they also have a review process to approve or reject submissions. If I remember they add their steemit user as one of the beneficiary of your posts when you create a post via their frontend. You could do it this way you have a frontend where you can post your submission and then the person who is paying for your upvote is one of the beneficiaries of the post. Hope that makes sense?
Which brings me to my next idea :) , the ability to pay for bidbots with an SMT. Maybe have a specific SMT for that purpose. Would really do the steemit economy good imo.
