Agreed. I gave up a couple sentences in and had to run it through Readability to read it. Hairline fonts (Helvetica Neue Ultra Light, in this case) are not really intended for body copy. Of course, the font choice is not the only thing that makes this practically illegible. It's too large, the leading's cramped, and it could probably use a max-width to prevent excessively long lines in larger viewports. Fascinating article, though!
