Hi, (I don't know if you'll find this useful or just blatant self-advertising -- it is probably a bit of both :-) It is a very recent paper arguing for a variant of /liquid democracy/, a kind of delegative democracy introducing a dampening factor that reduces the weight of votes that travel through long delegation chains. We argue that it might be a good decision-making system for online social networks. *Viscous Democracy for Social Networks - CACM Virtual Extension - June 2011* http://chato.cl/blog/en/2011/05/viscous_democracy_for_social_networks.html The link above includes a summary as well as links to the (paywall'd) article in CACM, and the authors' copy (free as in beer).
