Query: This is not economics!

This much hailed book is as close to Economics as Twitter tweets are to a novel. It's not that it skims the surface, the surface that it skims is not Economics but Sociology, Human Geography, Politics, Statistics, anything other than economic theory. Sure it's quite entertaining, and it might help you look at things in a different way, which is always a good thing, but anyone wanting to learn any Economics is going to be reading the wrong book.
