Well, I'm not (to date) much of a Yarn Harlot enthusiast.
That said, when I saw Knitting Rules! at a Dymocks, I picked it up.
I am such a knit geek, I relate to practically everything! I am struggling not to gorge myself and just read the rest in one sitting.
I do that with books. I can read a novel in a day if I am not careful. It's bloody expensive!
Anyway, I've enjoyed it terribly much. Funny, amusing and useful - who would have thought?!
