WikiNetNav is a new tool for wiki end-users to explore social networks implied through co-authorship, review changes made by other users, and to personalize and visualize their desired change notifications. This new graph-based tool will allow the monitoring of wiki pages as well as authors. Users will be able to visualize the social network of contributors so as to more easily identify and select contributors to monitor based on their interests. This also facilitates identification of experts or possessors of relevant tacit knowledge.
