I have the first version of this book and have noticed in the books stores that it has undergone a significant size change (smaller). I like the book. While I rely on the Camel for explanations, I find it is a great quick reference -- but then I'm a blasphemer that finds it easier to find things in books than perldocs.
As for the 'quality' demand on reviews I think we can let each reader/writer make that decision for themselves. I don't remember reading anywhere that reviews had to be of a particular quality.
