Amazon likes to recommend books to you using a phrase like this: “Customers who bought Ferret Husbandry also bought Ferrets for Dummies.” Jumping from book to book like this, you can build a web of interconnected books. What can you learn from such a network? And is there a market for a book called The Dumb Husband’s Guide to Ferrets?

Only a few books appear to be read by both sides. With all the talk about blue states and red states this election year, ask yourself, do you read red books or blue books?
