I love this book. It doesn't make a terribly large difference to me that it is Black Hat versus traditional; the book has pretty simple techniques and guidelines that make it easy to figure out what to do about different, otherwise-problematic situations that you might encounter in your own house/workplace. It's better than a "dummies" guide to me, as it's very straightforward and explains the rationale behind what you're doing very clearly.
