Identity is very lightweight in most current wikis. Many allow anonymous editing; others request log-in, but do not authenticate the provided identity. In this talk I will discuss the pros and cons of different approaches to identity in a collaborative environment, including such issues as faceted vs. unified identities and how new interfaces that highlight author identity can be designed. Different approaches are best for different purposes; the goal of this talk is to stimulate thinking about the range of possibilities and to help system designers understand what is best for their particular situation.
