Response to...This is often known as "collaborative filtering", and pops up in systems like NoCeM and GroupLens. What's cool is that you don't need transitive trust or even poster reputations (anonymity without so much vandalism!). Just give the right reviewers the reputation "good/bad judgment about which articles are worth reading"--and you can find them by reviewing some articles yourself and measuring similarity of answers. Etc,etc. The last 2 aussi elections have featured something called 'the worm'.Its a dial that the studio audience control at the main debates.Individually control and all results show as a wavey line(the worm) on TV for the masses.A very strong plunge in the worm when talk turned to the new VAT tax,the GST. Some biometric feedback on the political reputation of politicians. The fact barely 50% bother voting in the US and UK being another.Rating articles is possible at sydney IMC.Often abused IMO.
