I don't understand the infatuation with obscure irrelevant studies to make a point. None of these are remotely relevant to the page in question. Linking to sources isn't a way to escape basic common sense scrunity.

Basic common sense says the site has poor visual hierarchy. These links in the past several posts have been to highlight that the common sense understanding is that it has poor visual hierarchy.

The basic scrutiny agrees with me, and the sources are to help provide both subjective and objective reference that shows that, yes, the common person would prefer a more structured layout.
