The author mentions the second-order effect of SEO upon the web: an entire industry gaming their client's sites to the top of search results has debased the quality of the web overall.

The entire market analogy is busted because HN and reddit aren't markets and up/down votes aren't currency. You don't "spend" your upvote on something. You have an unlimited supply.
