translation.en: Let me give you an example. When I first published some of these data a few years ago in a magazine called Foreign Policy, one of the people who wrote in, not entirely in agreement, was Tom Friedman. And since my article was titled "Why the World Isn't Flat," that wasn't too surprising.  What was very surprising to me was Tom's critique, which was, "Ghemawat's data are narrow."
translation.zh: 我来给大家一个例子。当我在几年前 在一个叫《外交政策》的杂志上 第一次公布这些数据时， 有一位人物来信，对此持不同意见， 他就是托马斯·弗里德曼。他的反对是必然的， 因为文章标题是《为何世界不是“平”的》。 让我非常惊讶的是汤姆的批评内容， 他说，“沃特使用的数据面太窄。”
