My thought on this was to develop a generic review system (ie would work for anything with a url) that shows you subjective results based on your social graph &#x2F; trust map and weeds out bad actors by crunching the advogato algorithm.<p>The challenge is liquidity, ie how do you seed the network and content but if you can solve that you can operate a review service for a fraction of the resources currently being wasted on these red queen races.
