To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This book is not worth the cover price. If it were under five bucks, perhaps (perhaps!) I'd keep it. As it is, I am sending this book back.
The book reads like a dictionary of IT terms with no attempt to unify them into something that makes sense as a solution. For example, there's a short blurb on what Twitter is and about a page of what a wiki is. This is information that anybody can find using Google or any search engine.
Oh, and guess what... this book has no bibliography. Did the author really come up with all of this on his own? I think not. Well, come to think of it, maybe. After all, it doesn't seem to have any substance to it.
Ever wonder why some books here on Amazon don't have have a preview mode where you can look in for a sample, or have a Kindle version? I did. And now I know. What a waste of time.
