We are still working out the best patterns for web browsing. The web is still surprisingly young. That 20% will learn eventually. Make it easy on the eyes, space it out, consider your use of typography, and avoid TL;DR. These concepts seem like they will persist.

To use those design tenants we just need more space. If that means moving the meat of the page below the fold and keeping a nice hook up at the top then I believe that's the way future web design patterns will go.
