Look closer, the links and descriptions (in the tgp portion) are all different on each page and change twice per hour. I did however use the same template so it looks very similar as far as the visual appearance.
As far as pagerank value, google isn't the only search engine out there. I don't claim by any means to be a SEO expert but I've always had better results for my site from other smaller search engines instead of going after google, the same SE everyone else is competing for.
