Query: If you think Word of Mouth Marketing doesn't affect you, you're wrong!

Wow, this book was such a good read and comes highly recommended. I honestly don't think that anyone realizes how much we talk about our favorite and least favorite products in life - cars, shoes, shampoo, laptops, anything! This book is a real eye opener to why people talk/share the way they do and why every company who isn't doing using WOMM to their advantage needs to reconsider their marketing strategy!Overall, the book is so well-written. The author is witty and gives loads of examples, even coming up with a fake product to demonstrate the WOM impact. I loved it!
