Over the next seven days, David Mitchell will be releasing a short story called "The Right Stuff" in tweets. In 280 tweets of 140 characters or less each, to be exact. The author of the popular "Cloud Atlas" has a book coming out soon, and the tweet story will be set in the same universe. The Right Stuff will be revealed in 20-tweet bursts, at 7am and 5pm daily for the next seven days. My favorite bit: The story is being narrated in the present tense by a boy tripping on his mother's Valium pills. He likes Valium because it reduces the bruising hurly-burly of the world into orderly, bite-sized 'pulses'. So the boy is essentially thinking and experiencing in Tweets."
