Your friends have more friends than you do!

Steven Strogatz from Cornell is writing about the friendship paradox in social networks. Read this:

"You spend your time tweeting, friending, liking, poking, and in the few minutes left, cultivating friends in the flesh. Yet sadly, despite all your efforts, you probably have fewer friends than most of your friends have. But don’t despair — the same is true for almost all of us. Our friends are typically more popular than we are."

Don't believe it?  Read Steven's beautiful essay in the New York Times.

Steven has a lot more to say about (social) networks, and we will discuss some of his papers in class.
