Matt Weinberger explains why he could not leave Facebook: “First, because everybody uses it, my social life had come to be defined by Facebook invitations. … Apps on my phone use Facebook as a login. … On Facebook, you’re at the center of a network of friends, and friends’ friends, and friends’ friends’ friends. On Twitter, you’re just another user. The Twitter philosophy results in the kind of online harassment we have seen in GamerGate and the like. But Facebook’s more intimate setting means your life is basically always on display for the people who theoretically know you best.”
