The chances are that if you're considering reading this book you'll already be aware of (and probably affected by) what the authors refer to as the "Facebook Phenomenon"
The impact of social networking through websites such as MySpace, YouTube, Wikipedia, Facebook and (increasingly) Twitter is quickly rippling through society and is dangerous to ignore, particularly as a generation is emerging for whom such networking is the norm for personal interaction. It is this explosion in virtual relationships that the book explores. It's not just a book about social networking: also covered in significant detail is the challenge to the dominance of the CD thrown down by the arrival of file-sharing alternatives that call into question the fundamental concept of ownership in the domain of popular music.
At around 300 pages, what this book offers is a profound, learned and sociologically-driven overview of how individuals, organisations and society are beginning to be affected by the advent and development of social networking. The use of analogies such as the dominance exercised (and lost) by the Knights Templar will enlighten and amuse some readers, but irritate and confuse others, so it's a case of buyer beware!
If there is one particular weakness in the book it's the fact that the growth in social networking is so rapid that the book was practically out of date as soon as the printing ink was dry. (Twitter, for example is given a mere three mentions)
So who should buy the book? If you're interested in the overall impact that social networking is having on the 21st Century, and you're prepared to exercise your brain, you'll be educated and informed by the end of the book. If you're looking for specifics on the individual networking sites, or are perhaps thinking that the book will offer some light refreshment, then it's not the one for you!
