I was more interested in this book for the websites and apps it recommended, and I have to say I was very impressed! The reviews of each website contain relevant information, and the writer also refers you to other books and sources if you want more information on certain topics he doesn't cover. I also liked that he addressed concerns with security but giving a few tips on how to keep your information safe.
