This is a paper about knowledge, learning and the idea of community in what we call "hybrid workspaces". Hybrid workspaces "bring together physical place and cyber place" in communication networks (Castells, 2001, p. 131). Many people work in various kinds of hybrid workspaces. A person working on a production line might have real-time co-workers in their own town, just as a colleague might work in a hybrid workspace and rely upon others who communicate asynchronously via a website to help them solve problems. Hybrid workspaces, like most workspaces, are centrally concerned with the global production and diffusion of certain kinds of routine and innovative working knowledge. In this paper we think about knowledge as social action that is generated, mediated, negotiated and traded among people in the politically charged dynamic of hybrid workspace communities. We consider the ways people adopt, modify and are changed by the technologies they implement in these workspaces. We are especially interested in what people have to learn to know, and to be, to operate effectively in these hybrid communities, and what role formal, informal and non-formal education has to play in negotiating what counts as knowledge, and who can say so, in virtual workspaces.
