Topic Development in USENET Newsgroups

While computer mediated discussions, such as those that take place in USENET newsgroups, superficially appear to be analogous to verbal discussions, observation has shown significant differences. USENET topics are created, and they evolve, mutate, and become extinct in ways fundamentally different from spoken dialogue. These differences can be explained partially by the asynchronous nature of electronic communication, as well as by other factors unique to such wide-scale multi-user media. © 1998 John Wiley & Sons, Inc.
