Technological advances that enable seemingly endless information sharing, as well as various counter efforts that attempt to limit and control access to information, have prompted us to reexamine how industry-based practitioners of ethnography promulgate their research. A comparison of two distinct professional experiences reveals how varying degrees of information “openness” impact ethnographic work. One occurs within a large corporation in which research is proprietary and confidential. The second is an open source project supported by a Knight Foundation grant. In doing so, we aim to discern which elements of open source ethnography have beneficial applications in corporate environments. We present a “layering model,” as well as a set of questions to consider, as a way of determining which aspects of ethnographic research should be shared and with whom.
