The last decades have seen tremendous growth and transformation in the Internet's commercial landscape. Underneath this success, however, the underlying network architecture has shown a marked resistance to change; it is now described as stagnant and ossified. Numerous design proposals have been developed by researchers, implemented in code, and written right into the routers and end-systems...

Common to them all is a focus on the use of information and the use of experiments and quantitative methods for the analysis.

Ethnographic data from a "wrong place" helps challenge some...

Yet as advertisers and marketers know, our mistrust of words doesn't inoculate us against them.” These are the years of talking dangerously, and Nunberg is a sure guide to the pitfalls. With illuminating intelligence...

Through the work of constructing a field site, researchers define the objects and subjects of their research. This article explores a variety of strategies devised by researchers to map social research onto spatial terrain. Virtual networked field sites are among the recent approaches that are challenging conventional thinking about field-based research. The benefits and consequences of one...

This article reports empirical findings from four inter-related studies, with an emphasis on collocated sharing. Collocated sharing remains important, using both traditional and emerging image-related technologies. Co-present viewing is a dynamic, improvisational construction of a contingent, situated interaction between story-teller and audience. The concept of performance, as articulated...
