That's a great idea, but I'm afraid that curators would simply choose to not vote and move to the next post with trending potential. As a result, authors would simply stop posting a test question because they'd be afraid of getting no votes and not being seen...still.
I've been saying this since my first real view of the system: It all starts with the whales. If they don't take it upon themselves to more equitably distribute the rewards to quality writers, then it won't happen. As it stands right now, even if it's not true, the perception is that they'd rather use their bots and reward a select few users...and themselves for what most people are apparently seeing as sub-par content. They have the ability to make or break this platform. Right now, there are a lot of people who think it's broken. I'm not one of them - yet - but I'm not going to say that it isn't trending that way. Because I think it is.
Just look at the top trending posts right now. Five of the top 10 are directly about Steemit, and a couple others are closely related. That's a real problem.
