More thoughts on "great writing":
I can't remember why I started reading a review of a book about gardening...I have no interest in gardening...but for some reason I did, and it was a great review. Loved reading it. I didn't recognize the reviewer's name, but I looked her up and started reading her books. The first one wasn't a topic I was interested in, but I read it anyway, loved it, and it became a topic I was interested in. (It was a biography of St. Exupery.)
I've yet to read an RPG supplement that I would give to a non-gamer and suggest they read it just for pleasure.
