chapter 5 reading/response

In chapter five of The Social Life of Information, on page 119, the term epistemological, which is used in the context of a form of debate, caused me to not understand the context of the section of personal dis-function. On page 127, Brown discusses the central properties of the community of practice. As I continued reading, I was surprised to find that while getting the job done, people that were involved in the task, ignored division of rank, which then lead to forming a single group around a shared task.
