Query: Lacks clarity, gets lost in details

I use Plone a lot in my job and I bought both this book and The Definitive Guide to Plone by Andy Mc Kay.I find this book to be confusing at best, maybe because it tries to cover too much ground. When it describes the portlets, it goes on for SIX pages describing each portlet, with a screen capture for each portlet! It talks about REST for over a page, although this architecture has really nothing to do with Plone. Etc. Etc.All in all, it seems to me that too many technical editors have worked on this book, making it overly technical and complicated. Even the font they use make the content look cluttered!It is very difficult to write something clear and simple, especially for a very piece of technical software such as Plone. In my humble opinion, this book has failed in that regard.I almost never use this book on my everyday job. Get Andy Mc Kay's book, you'll get a much better value for your money.
