Concept: Use the technology behind Newsblaster (What is? It "automatically collects, clusters, categorizes, and summarizes news from several sites on the web") at Amazon. Make use of the recommendations system (based on your purchases) to see which reviewers are most like you, and the reviewer reputation system; add in the story merger, and create: A unique single paragraph review, customised to your tastes, on every single item on the Amazon site. And then use the same system, only on Punternet.
