Be sure to check out the special theme section on Social Network Sites, guest edited by danah boyd and Nicole Ellison! Volume 13, Issue 1, October 2007

Social network sites (SNSs) are increasingly attracting the attention of academic and industry researchers intrigued by their affordances and reach. This special theme section of the Journal of Computer-Mediated Communication brings together scholarship on these emergent phenomena. In this introductory article, we describe features of SNSs and propose a comprehensive definition. We then present one perspective on the history of such sites, discussing key changes and developments. After briefly summarizing existing scholarship concerning SNSs, we discuss the articles in this special section and conclude with considerations for future research.

Social software, software that supports group communications, includes everything from the simple CC: line in email to vast 3D game worlds like EverQuest, and it can be as undirected as a chat room, or as task-oriented as a wiki (a collaborative workspace). Because there are so many patterns of group interaction, social software is a much larger category than things like groupware or online communities -- though it includes those things, not all group communication is business-focused or communal. One of the few commonalities in this big category is that social software is unique to the internet in a way that software for broadcast or personal communications are not.

YouTube is a public video-sharing website where people can experience varying degrees of engagement with videos, ranging from casual viewing to sharing videos in order to maintain social relationships. Based on a one-year ethnographic project, this article analyzes how YouTube participants developed and maintained social networks by manipulating physical and interpretive access to their videos. The analysis reveals how circulating and sharing videos reflects different social relationships among youth. It also identifies varying degrees of "publicness" in video sharing. Some participants exhibited "publicly private" behavior, in which video makers' identities were revealed, but content was relatively private because it was not widely accessed. In contrast, "privately public" behavior involved sharing widely accessible content with many viewers, while limiting access to detailed information about video producers' identities.
