I know I'm most probably going to get blown out of the water here, but here's my 2cents.
"Function over Content"
A telephone directory is pretty banal content, but it has a function, and if you are looking for telephone number, a telephone directory will give you the "result" that you want.
Or put another way, is a 300 word article on fixing a washing machine better than a detailed step by step diagram encapsulated in a .jpg? Whats more functional? What gives the user the best experience and result?
I believe Google is and is trying to make these connections, or rather connecting the potential result with the function.
