Beth Simone Noveck has written a seminal piece on "Wiki-Government" for Democracy: A Journal of Ideas, and I recommend you read the whole thing. Noveck is Professor of Law and director of the Institute for Information Law & Policy at New York Law School and the McClatchy Visiting Associate Professor in the Department of Communication at Stanford University, who has been advising the U.S. Patent Office on its new open-source approach to involving the public in helping review patent applications, and that experience informs her vision. She lays out a powerful case for reinventing government with "civic software" (a term I once floated and still love) that "can shift power from professional sources of authoritative knowledge to new kinds of knowledge networks" and create a kind of "collaborative governance." I love it.
