Knowledge sharing between individuals has traditionally been conducted using faceto- face conversation. In the networked society – initially formed by telegraphs and the phone and nowadays powered by the Internet – many acts of knowledge sharing are carried out in a mediated fashion. While this typically introduces a number of problems in the knowledge sharing process, it also offers certain advantages. In this paper, we describe a framework for analyzing different modes of knowledge sharing. Furthermore, we line out the concept of “need-driven” knowledge sharing to address limitations in current mediated knowledge sharing approaches.
