I came across this article about BazaarVoice launching syndicated review content today and though thier offering may not apply to our specific market, the concept is one we have started to integrate for ourselves. Reviews and other methods of building a community or 'social networking' is proving to be a powerful traffic grabber.
People who offer products - affiliates or direct companies - could do alot with this added content and traffic source. It helps with number of pages and builds your authority, as well as more pages to get into organic results... seems like a winning method to me. Forum and review posters and readers also spend more time on a website.
I will follow this company's progress with interest.
