That's in order for the page to be rendered correctly from the start. I believe YouTube is using the same technique.

Because of the scroll-effect on the bacgkground, the animated flash buttons and the animated logo, the page might load a bit slow. And until it's fully loaded, it might not be displayed correctly.

This ensures that the reader is getting a nicely rendered page, instead of seeing how the page loads bit by bit if he has a slow connection.

Quoted from "Guza"

I would rather look at text while the page is loading instead of staring at the grey screen for 10 sec.

same here

workaround: if you dont load/use the css of the page you can read it properly without waiting for all the bloat loading
this also makes the site readable without JS (sites that are only static but still dont view anything without JS are )
other option is to block the bloat directly (with adblock), the great looking logo for example is a huge file for example, same with the background... blocking these improves loadingspeed significantly

fix for the stuttering scrolling: block
jquery.mousewheel.js
