As we move through the first decade of the 21st century, anthropological practice and research faces a series of methodological challenges. On the one hand, technological innovation provides practitioners with computerized methods of measuring and mapping social interaction. On the other, we are called upon to fall back on our basic ethnographic skills and to construct our programs and projects in consultation and collaboration with those we are working with, or learning about. Moreover, whether using GIS, intricate medical measures, or collecting oral histories, many applied anthropologists acknowledge that they must serve communities as well as learn from them.
