His advice is definitely for small or medium form writing. Places where you have substantial blocks of text. If you are trying to style headings or a web application then some of the ideas will apply but you should seek advice specific to that. For instance, the "give your text breathing room" is always going to be correct, but how much room you need is different for a small chunk of text in a button vs a large block of text. The context that it is placed in also matters.
