The book is good and well organized from management and business perspectives. But as a software developer, I expected that author will describe the JS code under-the-hood, or at least that he/she will give some insights about API & the JS core. I expected that the author will focus a bit on JS code and will give detailed explanation of well known GA's JS tricks. But simply he doesn't! He/She just keeps encouraging you to copy/paste! So, if you are a developer, this book for sure isn't for you, unless you have a quick task you have to accomplish with GA and you don't want to master the 'technology'. While, if you are working in some business fields and you are not interested in technical discussions, this book is certainly for you, it will make you integrate GA quickly and smoothly (with lot of code copy paste, I know you will love this). Anyway, It's worth reading, but don't expect it to be a technical book where developers are in author's mind-focus, lower your expectations a bit, and skip some chapters, they are there just for completeness, maybe you will not use their info in your whole life dealing with GA!
