Eastern Standard Tribe

Eastern Standard Tribe. Cory Doctorow. Tor Books,2004

From a review at http://www.sfsite.com/07b/ea180.htm

"Instantaneous global communication has produced a newly-emerging social structure in which people organise themselves not necessarily by the geographic area in which they live, but by the sub-culture they most personally identify with. Thus Art, who identifies with the culture of the American East Coast, has adjusted his personal work/sleep schedule to allow him to live in sync with people who live in the eastern United States. More and more people around the world are doing the same thing, producing a world where traditional boundaries mean less, and the effects of sleep deprivation are a truly serious problem."
