I thought this was interesting: Lawrence Quill writes:
“Citing a study that examined the habits of Internet users, Bauerlein (2008a) notes that people tend to follow an ‘F-pattern’ of reading when they read online (fast reading), a manner that differs significantly from the way people read books or newspapers (slow reading). On a web page, people will read the first sentence at the top of a page. But then they will descend quickly, slowing in the middle, then another sharp descent to the bottom ignoring the bottom right hand corner altogether. ‘‘People’’ notes Bauerlein, ‘‘scan, jump around looking for keywords, bullet points, pictures, color and typeface variations’’ (2008b).” (p.332)
