If you feature product reviews in your blog (or website), Chitika has a new product that looks extremely promising. Called ShopLinc, this is a really sweet way of marrying the products you are already talking about with an online store custom tailored to your content. In their words, "your shop features content from your website, blog posts or articles. So it's not just another shop, its your shop with your content."
I didn't quite get the concept until I went to the demo (link above), but now I get it. I think this could be pretty powerful for some people. You should check it out.
