As online purchasing and window shopping becomes more prevalent, seeing what other people think about particular products has grown in popularity as well.
True, not every website out there has online reviews. For instance, I've yet to read any reviews on the Weather Channel ("Man, your weather sucks!" or "That lightning storm was great, but we could have done without the exploding generator."). In the meantime, many sites that sell a variety of products are turning to the consumer to hawk their products.
