Tangentially related, I wish more websites and blogs looked like this now. It's elegant and modern but simple.
So its so elegant and modern that I came back to the website by searching for it so deeply xD
I do wish as voidUpdate has said that I wish for it to be a bit more centered but its overall great!
Much more practically, the best designs are the ones who don't demand of the user they be consumed in a single form across every scenario.
Looks like dog shit on mobile.
I agree that this general style is good, just without some of this page's fuckups.

This matches the max-width specified by the CSS. However, a smaller viewport width might be appropriate to increase the text size on mobile.
