Introductions and Requests: Rhetorical Strategies That Elicit Response in Online Communities

Online communities allow millions of people who would never meet in person to interact. People join web-based discussion boards, email lists, and chat rooms for friendship, social support, entertainment, and information on technical, health, and leisure activities [24]. And they do so in droves. One of the earliest networks of online communities, Usenet, had over nine million unique contributors, 250 million messages, and approximately 200,000 active groups in 2003 [27], while the newer My Space, founded in 2003, attracts a quarter million new members every day [27].
