As online groups grow in number and type, understanding lurking is becoming increasingly important. Recent reports indicate that lurkers make up over 90 % of online groups, yet little is known about them. This paper presents a demographic study of lurking in email-based discussion lists (DLs) with an emphasis on health and software-support DLs. Four primary questions are examined. One, how prevalent is lurking, and do health and software-support DLs differ? Two, how do lurking levels vary as the definition is broadened from zero posts in 12 weeks to 3 or fewer posts in 12 weeks? Three, is there a relationship between lurking and the size of the DL, and four, is there a relationship between lurking and traffic level? When lurking is defined as no posts, the mean lurking level for all DLs is lower than the reported 90%. Health-support DLs have on average significantly fewer lurkers (46%) than software-support DLs (82%). Lurking varies widely ranging from 0 to 99%. The relationships between lurking, group size and traffic are also examined.

In this study, we investigated people's relationships with AIBO, a robotic pet, through 6,438 spontaneous postings in online AIBO discussion forums. Results showed that AIBO psychologically engaged this group of participants, particularly by drawing forth conceptions of technological essences (75%), life-like essences (49%), mental states (60%), and social rapport (59%). However, participants seldom attributed moral standing to AIBO (e.g., that AIBO deserves respect, has rights, or can be held morally accountable for action). Our discussion focuses on how robotic pets (now and in the future) may (a) challenge traditional boundaries (e.g. between who or what can possess feelings), (b) extend our conceptions of self, companionship, and community, and (c) begin to replace interactions with live pets. We also discuss a concern that people in general, and children in particular, may fall prey to accepting robotic pets without the moral responsibilities (and moral developmental outcomes) that real, reciprocal companionship and cooperation involves. This research contributes to a growing literature on the human-robotic relationship.

The aim of this research is to develop an in-depth understanding of the dynamics of online group interaction and the relationship between the participation in an online community and an individual’s off-line life. The 21 /2-year study of a thriving online health support community (Bob’s ACL WWWBoard) used a broad fieldwork approach, guided by the ethnographic research techniques of observation, interviewing, and archival research in combination with analysis of the group’s dynamics during a one-week period. Research tools from the social sciences were used to develop a thick, rich description of the group. The significant findings of this study include: dependable and reliable technology is more important than state-of-the-art technology in this community; strong community development exists despite little differentiation of the community space provided by the software; members reported that participation in the community positively influenced their offline lives; strong group norms of support and reciprocity made externally-driven governance unnecessary; tools used to assess group dynamics in face-to-face groups provide meaningful information about online group dynamics; and, membership patterns in the community and strong subgroups actively contributed to the community’s stability and vitality.

One of the most challenging problems facing builders and facilitators of community networks is to create and sustain social engagement among members. In this paper, we investigate the drivers of social engagement in a community network through the analysis of three data sources: activity logs, a member survey, and the content analysis of the conversation archives. We describe three important ways to encourage and support social engagement in online communities: through system design elements such as conversation channeling and event notification, by various selection criteria for community members, and through facilitation of specific kinds of discussion topics.

I would like to extend my gratitude to a number of people. Any project of this magnitude requires a wide range of talents. I am indebted to Thawatchai Piyawat and Dick Seabrook for their consummate programming skills, and to Jantawan Noiwan for her statistical advice. Drafts of this thesis were considerably improved through the thoughtful comments and editing of Heather McDonald and Carolyn Davidson. Additional thanks go to mentors Tom Carey and Dave Hendry. None of this would have been possible without the interviewees and the members of the discussion lists. I thank them for their time, insight and participation. The research was carried out at South Bank University and the University of Maryland Baltimore County. I am grateful to both universities for their support. Finally, special thanks to my committee, Fintan Culwin, Xristine Faulkner, and Jenny Preece. i The goal of this thesis is to increase our understanding of lurkers and lurking in online groups by addressing three primary questions: why do lurkers lurk, what do lurkers do, and how many lurkers are there? Lurkers reportedly make up the majority of members in online groups, yet little is known about them. Without insight into lurkers and lurking, our understanding of online groups is incomplete. Ignoring,

Handwritten codexes or printed books transformed society by allowing users to preserve and transmit information. Today, leather-bound volumes and illuminated manuscripts are giving way to animated image maps and hot links. Vannevar Bush's memex has inspired the World Wide Web, which provides users with vast information resources and convenient communications. In looking to the future, we might again transform society by building genexes -- generators of excellence. Such inspirational environments would empower personal and collaborative creativity by enabling users to: . collect information from an existing domain of knowledge, . create innovations using advanced tools, . consult with peers or mentors in the field, and then . disseminate the results widely. This paper describes how a framework for an integrated set of software tools might support this four-phase model of creativity in science, medicine, the arts, and beyond. Current initiatives are positive and encouraging, but the...

What is the network form of online discussion groups? What are the topological parameters delineating the interaction on such groups? We report an empirical examination of the form of online discussion groups. We are interested in examining whether such groups conform to the Small World and the Scale Free models of networks. Support for these expectations provides a formal expression of growth, survival potential and preferential attachment in the connection patterns in discussion groups. The research questions were tested with a sample of over 8,000 active participants, and over 30,000 messages. We find that the social network resulting from discussion groups is indeed a Scale Free Network, based on In, Out and All Degree distributions. We also find that, for the same sample, discussion groups are a Small World Network too. As expected, the clustering coefficients for these groups differ significantly from random networks, while their characteristic path lengths are similar to random networks. Implications of the topology for the design and understanding of discussion groups include the stability and control of such groups, as well as their

E-commerce strategists advise companies to create virtual communities for their customers. But what does this involve? Research on face-to-face communities identifies the concept of “sense of community: ” a characteristic of successful communities distinguished by members ’ helping behaviors and members’ emotional attachment to the community and other members. Does a sense of virtual community exist in online settings, and what does it consist of? Answering these questions is key, if we are to provide guidance to businesses attempting to create virtual communities. The paper explores the concept of sense of virtual community in a newsgroup we call Multiple Sports Newsgroup (MSN). We first demonstrate that MSN does indeed have a sense of virtual community, but that the dimensions of the sense of community in MSN differ somewhat from those reported for physical communities. The nature of these differences is plausibly related to the differences between electronic and face-to-face communication. We next describe the behavioral processes that contribute to the sense of virtual community at MSN—exchanging support, creating identities and making identifications, and the production of trust. Again, these processes are similar to those found in non-virtual communities, but they are related to the challenges of electronic communication. Lastly, we consider the question of how sense of community may come about and discuss the implications for electronic business.

E-commerce strategists advise companies to create virtual communities for their customers. But what is involved in establishing and maintaining virtual communities? This paper addresses two questions: Does a sense of community similar to that sometimes observed in physical communities also occur in virtual settings? And how is a sense of virtual community maintained? These questions are examined in an intensive study of an established virtual community called MSN. MSN members experienced a sense of community, but the dimensions of sense of community differed somewhat from those reported for physical communities in ways plausibly related to the differences between electronic and face-toface communication. The experienced sense of community in MSN was actively maintained through the social processes of exchanging support, creating identities and making identifications, and the production of trust. Again, these processes are similar to those in non-virtual communities, but related to the challenges of electronic communication. The findings suggest a process model of sense of virtual community creation and maintenance that is simpler and more powerful than previous theories.
