Is there information in the article that you find useful or interesting? Or that someone else might? If so, then what does it matter that he wrote a book on the same topic and mentions it? Would it have been better if he'd written exactly the same article but not mentioned the book?

Fair point, I just worry about the prevalence of "stealth" advertising. For me at least, the article seems to boil down mostly to "Look what my lifestyle book did for this person". But if others are getting value from it then who am I to judge :)

If the article was valuable, it follows the book is even more valuable.
