"If your life is too easy and you want to create a never ending stream of tears and frustration you can try and inline the CSS that applies to elements above the fold and have the rest load in a separate CSS file."

Good read, not a ton of practical advice though.

I got a good laugh honestly. Nice article which is filled with interesting, although not necessarily useful performance ideas. Their site does load impressively fast at ~10ms page-load reported by Chrome.

Unfortunately, as a professional web developers, my clients never need such optimizations. They want new features long before they ever get upset about pages being sluggish in the second range. I'd love to be required to do more stuff like this, and I'm sure some people do, but the vast majority of the suggestions are looking for performance at all costs.
