I think part of our frustration with Amazon is that there is a sizable amount of clearly fraudulent behavior in their marketplace; addressing even the lowest hanging fruit (huge upswing of 5 star reviews across narrow time windows on a single product for one) would show good faith on their part, yet they don't manage their marketplace. Another issue that adds to the confusion: a combined five star rating scale on a product that has 12 different variations is meaningless. They could treat them individually, but choose not to.
