This book is a book I should never have bothered with, but I had hoped to pick up an idea or two from it. However, this book is extremely superficial, a lot of loose, unspecific talk for more than half of the book and then the briefest run-through of the various social media platforms that barely touches on more than each platform's user volume, in some cases who are the primary users. Nothing in regards to practical examples, things to look out for, dos and don'ts and such very relevant items.
The claims in the title "How to Skyrocket Your Business..." and "Master..." don't come close to being valid. This book appears to been written by someone who barely has used these platforms for business purposes himself, much less tried to promote a business using these surfaces.
Do yourself the favor and ignore this book.
