My system Quantified Prestige is the result of me thinking about how a reputation economy could actually be made to work. I’ve commented on Cory Doctorow’s statement about Whuffie being a Bad Thing and what Quantified Prestige has to do with it here:
Also, Quantified Prestige is intended to enable multi-dimensional reputation scores, either via multiple different reputation networks, or via different Prestige Scores within one reputation network. That would also enable the generation of data that could be visualized vie reputation flowers. Great idea, by the way!
