Interesting, but I still don't see how the fundamental trust issue is covered by the proposed solution. The system may reduce the chance that a reviewer is a shill, but it in no way establishes their credentials. All you know is that they purchased the product - and frankly this already suggests a level of bias. People will continue to value the advice of those they know much more highly. The challenge is to establish a comparable level of trustworthiness in online reviews.
