I would have loved to have seen this book as a learning tool to programming the site. But in essence this book is more a means to identify potential design issues, and what the author thinks are good ways to go about doing things. I found it extremely hard to run the code, maybe a chapter by chapter breakdown of code would have been handy, but if i ever get stuck at some point, then i was lost. This book doesnt have the exact code and explaining what the code should do, and how it goes about doing it, so in essence, it was really a try to figure it out yourself kinda deal. I found it a mess.
