While the article is interesting, I find the layout of this website infuriating. A narrow strip of text, each line holding ~a dozen words makes it so much longer vertically than it needs to be, on desktop. I ended up using Inspect Element to change the width from 600px to 1200px, to fill up the most comfortable reading area on-screen.
Sorry to hear that. I built it that way because I prefer reading narrower columns of text (maybe because I read a lot of magazines and newspapers, who knows).
Fair enough, if that's what you prefer than you might as well, it's more of a personal preference. My main monitor is an ultra-wide, so it ends up using less than 20% of the total width. Though I can see it being tough to have a good solution that works everywhere.
The general recommendation is the keep the measure of the page fairly narrow since studies show that reading text that is very wide is harder than reading a narrower column of text. So looking at the layout from a best practices point of view the author made the right call.
