I love it. The distinctive voice behind the words. Archaic and a bit professor-like in it's way but never cold or impersonal. Also of great import here is the advice given to those looking for it, gems of knowledge strewn throughout for the observant reader.
Pay close attention to these words from the above excerpt, "Be imprecise and give only vague hints" and "Always roll the die, even if you know nothing can be heard. Always appear disinterested regardless of the situation."
These are words all DM's should heed, and not only in regards to hearing noise. All this in less than two inches of the book's column space. Perfect.
