Query: Verbos : Thick book, thin in useful information

I tried reading the book (up to chapter 8) still could not find a piece of useful information written properly or completely. Vague writing. I don't think the author has actual experience Ajax or design patterns ,he talks about.The chapters and sample codes looks more like written by a beginner . Too much plumbing and bad coding practice.And did I said verbose ?
