The ad revenue model requires a lot of SEO friendly pages to be in search indexes. I don't mind ads or that model in general.

A lot of the answers on pages are outdated but they have no incentive to cleanup old content if its going to affect their bottom line because they will have less indexed pages.

This means I get much more noise when trying to find something so I go elsewhere.

But won't that be self correcting if people bounce away from old (less useful) content? That would negatively affect SEO, I'd think.
