Product review (5 stars): Insightful & Very Useful!
I teach a class on innovation and I used the Necessity of Strangers as one of the required books. The students loved the book. The book is an insightful piece of literature that turns the common knowledge of networking on its head. The main point of the book is that random strangers are able to be much more beneficial in the growth of a product or business, because strangers have outside perspectives without bias.

I would highly recommend the book. Also, Mr. Gregerman is a wonderful public speaker!
