I agree. The article says: "MarketRank is built on the analogy of the market. An object with a higher market value is probably better." This is already how SEO works: if you get a link from another website to your content, it's like a "vote" for your content. A vote from a website with lots of votes is worth more. The result: This system is intensely gamed. People and businesses buy high-ranked domains and create private blog networks to set up backlinks to content that companies want to rank. Billions of dollars are at stake. It'll take a lot of effort to come up with something that can't be gamed. I appreciate the effort, but I don't think this is it.
