The chapter investigates an actionable context of knowledge networking, from the perspective of sustainable development which should accommodate the building of communities in cyberspace so much exemplified in today's Internet and World Wide Web. The premise of this exploration is that members, or participants, in any community are engaged in learning that is critical to the survival and reproduction of that community. Through community participation, learners find and acquire models and have the opportunity themselves to become models and apprentices of others. This investigation provides a basis for thinking about the possibilities of a virtual community and the dynamics of its construction across a variety of computer-based contexts. The design and refinement of technology as the conduit for extending and enhancing the possibilities of virtual community building is an essential issue, but the role of the individuals as participants in such a community is as important. The idea of sustainable knowledge networking is to bring about continual learning and change for the community in need. The emergent challenge of such a mission is to de-marginalize many of the non-technical issues of building virtual communities for knowledge transfer and learning. The chapter concludes by reiterating the challenge of expositing what it means to create an appropriate context of knowledge networking through which purposeful actions can be supported with the elaboration of suitable information technologies. © 2009, IGI Global.
