The web was intended to be a collaborative environment where users could exchange ideas but has turned into a read-only environment. The same is true for corporate intranets. In this paper we examine whether the removal of this read-only limitation can facilitate knowledge sharing. By installing a wiki in a corporate intranet, we intervened in an organisational setting and studied the results of this provocation. We found that the intranet transformed from being a semi-static bulletin board to a dynamic exchange forum for internal information. Our conclusion is that when editing becomes as easy as surfing people who want to share knowledge can indeed do so on a corporate intranet.
