When cultural commentary turns its gaze to online technologies, it grows dated in the blink of an eye. It’s like watching Joan Rivers and the accelerating pace of her plastic surgeries. The minute one thing gets tacked in place, something else droops. The author of the commentary either has to perform periodic updates to hold up the droopy arguments, or the author has to let go, knowing that their work will end up on a great garbage heap of theorizing and speculation which, if they’re lucky, will one day pique the curiosity of future anthropologists and historians. It’s seven years since Andrew Keen published The Cult of the Amateur and already I feel like such an anthropologist. How fast the world turns. He offered an update in 2008 with a forward and additional chapter, but, so far as I’m aware, there are no more updates; he’s moved on to other books.
