For an ever growing class of people shopping is becoming a science. Of course in any scientific endeavor, resources that aid the pursuit of knowledge (or in this case selvedge) are needed. That's where PowerReviews comes in.

PowerReviews aims to make it easier for consumers to make informed decisions, and easier for retail sites to close the sale. They do that by providing PowerTags which allow users to quickly and accurately provide a review for a product. Those reviews are then used to judge a products usefulness to other customers. PowerReviews provides ‘trusted’ comments and reviews for client sites, after all, a product is  a product, no matter who is selling it. If it warrants a good review then any site that sells it should be able to leverage that information.

In the demonstration they've set up at Buzzillions.com, the system is quick and intuitive as it narrows down the suggested products based on what you say you want. Based on my needs (as assessed by exceedingly short mini surveys) the system scanned through all of the available inventory to find the camera which matched my preferences. Partly because my professional photography career ended with that mishap in Gary, Indiana and partly because I stated I would be a casual user, the PowerReviews interface removed the thousand dollar Nikon D200 Digital SLR Camera right at the start. Gradually, contender after contender lost their bout with my picky taste, until only an ultra thin 3.2 mega pixel Hello Kitty camera was left standing.

With their system's ease of use and the naturally trustworthy nature of the verified buyer as a featured critic/reviewer, PowerReviews is a deal closer.
