The Knowledge Society Network (KSN) "takes advantage of new knowledge media to maximize and democratize society's knowledge-creating capacity" (www.ikit.org/KSN). This article synthesizes the principles and designs of this network which were initiated over 15 years ago, and presents an exploratory study of interactions in the KSN over four years, elaborating different network structures and the potential of each for knowledge advancement. Four major sub-network structures for participant and idea interaction are described, as reflected in social network analysis of discourse in the KSN. Strengths and weaknesses of work within each sub-network were identified with suggestions for creating a more dynamic, sustained network for knowledge advancement. (Contains 7 figures and 7 tables.)
