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 is the second book I have decided to review. I have decided to do so inorder that others may avoid my mistake. The book is banal. It goes on and on, creating category after category of needless taxonomies. Nothing even slightly new or interesting. Additionally it suffer the problem of all "internet" books. It was hoplessly outdated by the ime it hit thw shelves. Someone exceptionaly tiresome wrote a phd thesis, invented jargon and then decided to turn it into a book.
