The graphic opening the "Typographic Terms You Should Know" section is seriously broken. Arrows point to all sorts of wrong things. With a graphic like that, on a topic so graphically important, my rule of thumb is to disregard the article rather than spend the time to discern what is true and what is false in the text. But if you're interested in typography, by all means buy "The Elements of Typographic Style" which is a sound and beautiful work on the subject.
