The point isn't that the web should be mostly text, but that it shouldn't comprise of layers and layers of unnecessary fiddle-faddle that doesn't add anything useful to the end-user's experience.

If you can convey what your trying to convey with a JS-less (or even just JS-lite) 2-page website, then don't build a monolithic, scroll-hijacking, background-parallaxing fireworks show of a website, tied together with the most tenuous of Javascript libraries.

I'm all for the web as an application delivery platform, but not every website, or application, needs so much bulk.
