“Perfectly placed to tell us what’s really new about [the] second-generation Web.”—Los Angeles TimesBusiness visionary and bestselling author David Weinberger charts how as business, politics, science, and media move online, the rules of the physical world—in which everything has a place—are upended. In the digital world, everything has its places, with transformative effects:• Information is now a social asset and should be made public, for anyone to link, organize, and make more valuable.• There’s no such thing as “too much” information. More information gives people the hooks to find what they need. • Messiness is a digital virtue, leading to new ideas, efficiency, and social knowledge.
