We don't, or I hope we don't, form friendships at random on Facebook. The technology is overlaid on a pre-existing matrix of relationships that we have, and those relationships are what the technology doesn't quite displace. Those relationships are why we get far fewer than 95 percent of our friends being located in countries other than where we are.
因为我们不会，至少我希望我们不会， 在Facebook上 随便乱交朋友。科技虽然覆盖了 我们早就形成的人际关系， 但这些人际关系恰恰是科技 所无法替代的。正是这些既有的人际关系 我们才没有高达95%的朋友 是来自异邦。
