Thanks for getting back to my comment. Reading back my comment I might have been a bit harsh, I am sorry about that. The level of detail in the compression and caching bits were very detailed, thanks for that.

What I was most interested in technically is the part about 'Prioritize visible content'. You talk about "loading third party scripts later, and generally keeping the above-the-fold content small and fast". From this I make out that you do not load images below the fold, etc. I was wondering what you do technically to make this happen. Also, how would you load fonts after the first paint, etc. Also, from what I remember, when you inline your CSS you make caching the CSS separately from the HTML impossible. What would you do when you want to have a quick first paint, but also want to leverage having CSS in its own file?
