That's tempting, but I still don't think it should. There would still be the quest to go viral. "Quality" would still be determined in the aggregate, which means that your income depends on appealing to the widest audience possible, which means high quality niche bloggers still don't get paid much.
Metrics are hard. Just making sure they reward one particular desired outcome doesn't mean you'll escape the unintended consequences.
Also, note that we are past the point of being able to reasonably able to manage any of this. Today, you'd need to come up with a reward function that cannot be maximized by AI. (And lest you think you can fix that by using site visitors to evaluate, most of them will be bots too.)
