I first heard of ethnography in Sociology 101. In his sonorous voice, our professor regaled us with tales of intrepid anthropologists immersing themselves in little-known cultures in exotic settings. We discussed Margaret Mead's seminal work, Coming of Age in Samoa. We examined the rigors of fieldwork, the tension between observation and participation and the challenge of analysis. It was a great class and I even opted for Soc 102. And that was that. Ethnography faded into the recesses of my mind until reawakened with a start a few years ago when I began hearing it applied to Web design. And it scared me spitless.
