This is still slow as shit, why? It seems to be running under php when the whole thing could've been generated with jekyll and maybe even pjax'd to make navigation even quicker.
Any website "could be generated with jekyll" but you're totally ignoring the benefits of maintaining content with a dynamic site.
Just on HN, right now it's close to the #1 position; likely this site is getting hit with massive traffic as we speak, from diverse sources. Wait until that dies down before passing judgment.
