| Interesting. Do they have the concept of "transitive trust"? (Is there a better term for that?) Let's say I want to buy some new camera. I'd like to express something like: - People on HN, I trust for 80% (say, because of the technical nature of the product) - Friends on facebook I trust for 40% - Friends of friends on facebook, I trust for 10% Then using this spec, I'd like the system to come up with a sorted list of cameras, with ratings. Would this be possible without privacy issues? By the way, if a rating system turns out to be robust, we could potentially use it for rating politicians :) |
