Various people on our blogs have talked about how useful a whuffie concept would be (see especially Vassar on reputation markets. I agree that Less Wrong's karma scores encourage an inward focus; however, the general concept seems so useful that we ought to consider finding a way to expand Karma scores beyond just this site, as opposed to shelving the idea. Whether that is best implemented through facebook or some other means is unclear to me. Can anyone link to any analysis on this?
