I read a book years ago called "Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives" that talked a lot about this. A lot of opportunities in our lives come from two or three levels out in our social circle. IIRC, the book specifically mentions friends of friends as one of the most common ways to find jobs.

My favorite thing they talked about was how behaviors travel through social circles. A person you may not even know quitting smoking or losing weight could be the catalyst for you doing the same thing.
