"David Weinberger, senior researcher at the Berkman Center discusses his latest book, *Too Big to Know: Rethinking Knowledge Now That the Facts Aren't the Facts, Experts are Everywhere, and the Smartest Person in the Room is the Room*. Knowledge used to be a more straightforward matter than it is now; answers came from books or experts. But in the Internet age, knowledge has moved onto networks. There is more knowledge than ever, but it is different: topics have no boundaries, and disagreement is much more prevalent. Weinberger argues that this is not a cause for despair however, and he explores how business, science, education, and the government are learning to use networked knowledge to understand more than ever and to make smarter decisions than they could when they had to rely on books and experts alone."
