The article starts, "Nestled in the hills of Mountain View", which is worrisome, because as anyone with even a passing familiarity with Silicon Valley geography knows, Mountain View is mostly flat. And Google's Mountain View offices are located on reclaimed baylands, which are especially flat.
I wonder if the article authors were thinking of Xerox PARC's offices in Palo Alto's hills? Or the road named "Sand Hill Road" that used to have some venture capitalist offices? Other than those offices I can't think of any significant hill-based offices in Silicon Valley.
