Well, this book was quite disappointing.
At first, I liked how the author was able to tell the story and how he has connected the pieces together, but he has perpetrated huge mistakes like, for example, forgetting how some first generation googlers were vital to the success of the company.
I am talking of people like Eric Veach, who created the algorithms for AdWords, Jeff Dean, who created important infrastructure tools, Paul Buchheit, the Gmail creator and many, many other googlers. Fortunately, Craig Silverstein and Craig Nevill-Manning were not forgotten but the author barely mention their names.
Did you know that the "Don't be evil" motto was created by Paul Buchheit and Avid Pattel? Well, this fact is totally ignored by the author! If you read the book it will look like it was created by Brin and Page. Even Wikipedia is more accurate than this book.
