But to your points. I think the problem with your analysis is that it forgets that the real driver of the junk is the advertising environment. The SEO links were profitable because the advertisers were willing to pay a few cents for space on those pages. Yes, the incentives are changing for the teenagers who are churning out text and adding seo links to their stable of cheap websites, but the advertisers are going to find a way to manipulate consumers that's compatible with the new order. I don't know what that will be, but whatever it is will depend on information pollution just as much as the current one.
