Mon Nov 14 14:41:57 PST 2005 When running a content service (like Wikipedia) where contributions of content are solicited and then re-disitributed.... Run ads and then pay the contributors. The problem is: how much do you pay contributors? Pay them out of a pool of money. A cut of the ad revenue? How big a cut? Have them self-rate the value of their contribution. The accuracy of the self-ratings can be checked by: A paid staff that checks ratings randomly. Or by volunteers drawn from content creators.
