Is this proposing simply that googlebot merely a web-rendering engine (a web browser) or is it saying that googlebot is crowd sourced web crawling performed by everyone using chrome?
It sounds like the former, which is rather boring and kinda obvious, since the ability to crawl js-based websites requires "a browser" of sorts to render the content...
Meta: That blog as got to be one of the best examples of terrible design - intrusive pop overs, buttons that constantly shake (<blink> tag anyone?), icons that randomly rotate to distract you and overloaded scroll bars that I can't grab.
Just. Stop. It.
Using the mouse to scroll at a good pace is impossible. It always skips over bits and does the floaty thing.
