This document discusses the creation and use of a wiki to build a research community at De Montfort University. [The wiki was created] to share tacit knowledge and expertise among research students and early career researchers. However, the wiki saw little interaction from users despite many views. Lessons learned include the need for strategic integration, clear goals and vision, consideration of users' needs and attitudes, and ensuring tools fit with existing resources. The conclusion is that librarians should not force new technologies where traditional methods may be better, and that web 2.0 use should be researcher-driven.
