Paul Miller, a writer for The Verge, somewhat recently decided to take a year off from the Internet. You can call it a stunt if you'd like to - but it is turning out to be one of the most interesting public experiments I've ever seen online.
A recent piece and video by Miller was Against the future: inside the Jewish anti-Internet rally. Incredibly interesting, fun to watch, and definitely worth your time. And people are lining up to see what Miller covers next.
You can read all of Paul's work on The Verge from his page. Presumably he and his coworkers have figured out a system of publishing for him. I secretly wish there was a weekly printed newspaper that could be delivered through the post of all of Miller's entries for the week.
