I'm on non High DPI screen (2560x1440 @ 32") with a dot pitch of 0.27 and the typeface used for the body text and headings renders really badly, in the heading worded 'Paragraph' the letter 'A' is almost unreadable. I didn't read the article, why should I, when it clearly doesn't (presumably) follow it's own advice?
