I will give this one 3.5 stars. I think it's somewhat overrated.
I listened to this book on audible - term is starting again, and lots of driving...to work, kids, etc... and so I'm going to be listening to a lot more audiobooks.
This book, in fact, was well suited to audible, because it is long (quite long) on anecdote, and rather short (and superficial) on analysis.
Hence, 3-stars.
An intersting topic, though.
