Shareable: Trust is Currency For Peer-to-Peer Marketplaces
Excerpt:
"eBay has proved how the trust we typically form face-to-face can be built and assigned online by creating the grandfather of reputation systems, the Feedback Forum. After any transaction, buyers and sellers can rate each other using a simple points system (1,0,-1). Once users reach a certain number of points, they receive a star attached to their screen name, indicating their trustworthiness. The "silver shooting star" indicates the highest rating.
With around 98 to 99 percent of trades receiving positive rating the eBay approach seems to work and has been copied and adapted to a lot of other projects. One of the most common complaints with eBay is the use of nicknames instead of real names, and this is where the use of social network profiles can be a handy extra in the reputation system"
