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 analyzes reviews to verify trustworthiness.
I enjoyed reading about the various topics; however, I was distracted by the numerous grammatical errors, wrong words, missing words, etc. I did appreciate having links to source materials, but I would suggest more attention during the editing process.

This was a very good book with many facts. Each fact has a link to reference an article about the fact. Unfortunately, many of the links are to Wikipedia. Other that that, I thoroughly enjoyed reading this book.
