The shift from interior to exterior lives

From Mark Dery’s response to R.U. Sirius’ “Is The Net Good For Writers?” (10 Zen Monkeys: 5 October 2007):

But we live in times of chaos and complexity, and the future of writing and reading is deeply uncertain. Reading and writing are solitary activities. The web enables us to write in public and, maybe one day, strike off the shackles of cubicle hell and get rich living by our wits. Sometimes I think we’re just about to turn that cultural corner. Then I step onto the New York subway, where most of the car is talking nonstop on cellphones. Time was when people would have occupied their idle hours between the covers of a book. No more. We’ve turned the psyche inside out, exteriorizing our egos, extruding our selves into public space and filling our inner vacuums with white noise.
