I like this idea a lot.

We have to remove the economic (and time) penalty/opportunity cost of flagging and curating this site.

I spent several hours flagging child porn and plagiarism just 2 days ago, but I would have been much better off (from a personal perspective) if I'd spent that time authoring posts or replying to my commenters.

Hell, the people that do this for police stations have to be put on rotation so their minds don't explode. It's horrible work. Plus, I was probably doing something illegal by even being in the posts to flag it...more unrewarded risk.
