Query: Excellent Subject, Poor Presentation

With Michael Kaplan's contributions to other technical books by the likes of Paul Litwin and Ken Getz, I expected a bit more. It suffers from the lack of good, solid editing. He rambles over some points and glosses over others. I can only recommend it to people who already have a slightly better than basic understanding of the material. This isn't a book a novice or hobbyists could learn from without a great deal of effort. For them I would suggest waiting until someone else tackles the topic and does so a little more clearly and a lot more concisely.
