Why Wikis at NASA?

“The NASA workforce is hungry for ways to improve collaboration. Wikis can help–and are helping–to do that. These powerful tools exist at every NASA center and across many levels of organizations, from wikis running on a temporary server for a team of five to others for the benefit of an entire field center. There are grassroots, bottom-up systems, originating to meet a particular need for a specific project or group. There are top-down institutional systems, provided for the benefit of a larger organization. Among other uses, they are helping project managers promote better communication within their teams, and engineers collaboratively document the results of their work.” More at open.NASA.
