“The idea behind ProductWiki is to create collaborative product reviews that boil all the judgments about a product into one single review. It avoids revision wars by requiring every reviewer to list both pros and cons, and then every other ProductWiki reader can vote on each pro and each con until a consensus emerges.
“Last week, the site turned on three new features which Ismail hopes will allow him to create the ultimate “product graph” (this is like a social graph for products, showing how products are related or connected to one another). Reviewers can now identify competing or related products, and vote on which ones they like better in a head-to-head, A-B fashion. The third feature is a product rank derived from the first two features. For instance, based on 15 votes, the iRex iLiad beats out both the Kindle and the Sony Reader in the e-book category (so far).”
