"Wall of text" is usually reserved for people who don't use paragraph breaks; such a complaint is unfair on a perfectly well-formatted page. If you want it narrower, maybe make your window smaller?
IMO, it's almost impossible to stay focused when the text is poorly formatted as it was in this article. With just a couple of lines of CSS the readability would increase tenfolds.
I shouldn't have to make the window smaller in order to be able to read the authors post. If people find the formatting too frustrating, it's their problem as they want to convey a message to me, not the other way around.
