Did you ever get criticized for some­thing you tried that worked out? When we pioneered customer reviews, it was incredibly controversial. I got letters from publishers saying, “You don’t understand your business. You make money when you sell things. Take down those negative customer reviews.” We’ve never done anything of real value that wasn’t at least a little bit controversial when we did it. But if you want to be a pioneer, you have to be comfortable being misunderstood.
