(TinyURL.Com/RevTre = "reverse tree")
.
The basic idea is the inverse of a "phone tree". Instead of one person generating content and relaying it through an ever-expanding tree of volunteers, lots of volunteers collect information and filter only the very best up to the next level, so the one person at the top gets the best of the best of contributions and doesn't have to waste time dealing with the majority of fan mail etc.

The trick to get people to work hard at pleasing the end-recipient / target (person or newsfeed etc.) by their efforts filtering stuff for that end-recipient to see, is to use a truth-futures market whereby people put a "price" on each item being filtered, that "price" being the probability that the end-recipient will like to read the item. The market "price" for an item, rather than any one individual's opinion, is used for placing the highest-value items in the target's BestInBox. The funds that can be earned for good estimates, or can be lost for bad estimates, are the incentive for good filtering on behalf of the target (person or newsfeed etc.).
