This book is very, very comprehensive, though dated the movement it is printed. If a person had only one book on social media, this could be the one. Well worth the audible price. Also, there are another hundred links or so that the author has to read out for even more information. In the print d book, there are scan codes for all of these, which isn’t as easy as it should be, if you are reading a book this size on social media. This book could be a great textbook, actually, as long as a new edition is printed every year to keep up with the rapidly changing subject.
