I bought her book for my wife shortly after she started taking an interest in playing. My wife had been joining our group for a few sessions, and seemed into it, but I thought Ms. Mazzanoble's book would be a good way to say "see, you're not the only girl who does this, and it's not that weird."Ms. Mazzanoble is more active in the flavor area, and more specifically, in bringing new players (including more female players) into the fold. She isn't a number-crunching game designer and shouldn't be criticized as such.
My wife loved the book, and has since handed it off to some of the other wives of players in our group as a way to say "this is what your husband is doing, it's not that strange." Hell, even my mother-in-law has a better understanding of what we're doing when we're at my house once a month rolling dice thanks to the book.
I read the book myself, and yeah, it's definitely not for me (not just because I'm XY). It's for a newbie, its for a female. But it's an entryway into the game, and that's a GOOD thing.
(Plus, I'm partial to Shelley. She and my wife have become pen pals of sorts via email, and I think it was thanks to her direct influence that my wife is now trying her hand at DMing.)
