“We’re in a culture right now of sharing your experience. It all harkens back to the first point, in 2007, when two things happened simultaneously: Apple announced its first iPhone, which literally put a computer into every person’s hands, and Facebook came out of its university setting to become public, so that you could find out for the first time, on a 24/7 basis, what your colleagues, friends, neighbors, and family members were up to, and get their input on what they were doing with their leisure time.”
