This depends rather on what the purpose of scoring is. If it is to filter one's reading, there is an inherent contradiction: * the reader wants some filtering, so they can just read the good stuff * the filtering is done by the readers, which requires they read more than just the good stuff How effective can this ever be? It seems a weakness in all public-contribution-based systems (including Google search to some extent, because of page-rank . . .). (I posted this thought before somewhere, but I don't know if it wasn't thought good, or that no-one much read it.)
