From Usenet to CoWebs

Book excerpt: Beginning with a brief outline of Usenet's general structure and development over the past few years, the book addresses the problems of exploring virtual communities and distributed information systems in general, and of finding information in electronic information environments. It covers traditional approaches such as information filtering, collaborative filtering and information retrieval, outlining their successes and failures, and discusses the prospects of novel approaches such as visualisations of social processes and social navigation.
