I am looking for product review web sites right now. Looking to harvest data on different product areas and feed it back out to users. I am not looking to harness the traffic, it will go to the source of the reviews. I do this to get data and statistics and ultimately provide value to end-users.
4 out of 5 sites I come across have reviews but do not have an RSS Feed. I understand that some people are worried about their proprietary data, well.....get over it. RSS will generate new users and syndicate your content beyond your web site.
If you can't figure out how to have an RSS feed, go get a Wordpress blog and start using that!!
