The rise of the Internet has spawned the prolific use of the adjective “virtual.” Both the popular press and scholarly researchers have written about virtual work, virtual teams, virtual organizations, and virtual groups. But perhaps one of the most interesting phenomena to come to the forefront has been that of virtual communities. Many definitions of this term have been proposed and the term has been used in many different ways. This article will examine some of the most popular definitions and guidelines to understand what truly constitutes a virtual community. To define a virtual community, one needs to first examine the two words separately, particularly the sociological definition of “community.” The German sociologist Ferdinand Tonnies, in his 1887 book, made the distinction between two basic types of social groups: Gemeinschaft (community) and Gesellschaft (society). The former was often exemplified by the family or neighborhood (Tonnies, 1957). Sociology literature also often refers to the definition given by George Hillery, who reviewed 94 different definitions in academic studies. Three elements were common to the definitions, namely that community (1) was based on geographic areas, (2) included social interaction among people, and (3) had common ties such as social life, norms, means, or ends (Hillery, 1955). Thus the term community typically connotes a group of people within some geographic boundary, such as a neighborhood, or perhaps smaller subsection of a larger city. Further specification might have defined a community as a group of people within the geographic boundary with a common interest, such as the Jewish community of Brooklyn or the physician community of London. Therefore, members of the community were drawn together by both local proximity and common interest, even if the interest was in the geographic area itself. The term virtual, precipitated by the advent of information technology, and specifically, the Internet, means without a physical place as a home (Handy, 1995), or that which is electronic or enabled by technology (Lee, Vogel, & Limayem, 2003). Information technology therefore has expanded the means by which the social interaction in communities can be accomplished. While for most of human existence interaction was strictly limited to the face-to-face medium, social interaction can now be accomplished virtually, thus eliminating the necessity of being physically close enough to communicate. This type of communication is called computer-mediated communication (CMC). Combining the two terms together, thus, would mean eliminating the geographic requirements and allowing that the social interaction would occur virtually, that is, via information technology, among people with common ties. In fact, people have been coming together in virtual communities on the Internet for over 25 years. Usenet newsgroups, started in 1979, are widely regarded as the first virtual communities on the Internet (M. A. Smith, 1999), and The Well (www.well.com), started in 1985, is often referred to as an early exemplar of virtual community (Rheingold, 1993). Virtual communities may be part of a long-term shift away from geographic ties to common interest ties (Wellman & Gulia, 1999b). Formal definitions and understandings of the term virtual community still remain problematic, however (Lee et al., 2003). Perhaps the most cited definition is that of Howard Rheingold, a prominent author, consultant, and member of The Well: Social aggregations that emerge from the Net when enough people carry on those public discussions long enough, with sufficient human feeling, to form webs of personal relationships in cyberspace. (Rheingold, 1993, p. 5) Common to many of the definitions is the presence of shared interests or goals (Dennis, Pootheri, & Natarajan, 1998; Figallo, 1998; Kilsheimer, 1997). With the advent of information technology, locating/contacting others outside the local community has become relatively easy, especially when one seeks others who have a unique or uncommon interest. It may be that technology makes it easier for communities to form. For example, it may be difficult for someone interested in traditional bowhunting to locate others with the same inclinations by popping into the local tavern or socializing at a church function. However, a simple search in Google reveals a vibrant community centered around such an interest (www.bowsite.com/). There are virtual communities for nearly every interest that comes to mind, from medical afflictions (e.g., breast cancer, Parkinson’s, Down’s syndrome) to hobbies (e.g., coin collecting, wine, saltwater aquariums) to professions (e.g., nursing, law, finance). Implicit with the notion of community is some permanence among members and frequency of visits by members (A. D. Smith, 1999). Virtual communities must have a sense of long-term interaction (Erickson, 1997), not a place where people go only occasionally or where there are always different people. It is not uncommon for people to develop strong attachments to virtual communities, visiting them often enough to be described as “addicted” (Hiltz, 1984; Hiltz & Wellman, 1997). The members often feel part of a larger social whole within a web of relationships with others (Figallo, 1998). Indeed, many researchers have considered virtual communities as social networks (Hiltz & Wellman, 1997; Wellman, 1996; Wellman & Gulia, 1999a). Ridings et al. (2002) offer a comprehensive definition that incorporates the afore-mentioned concepts: Groups of people with common interests and practices that communicate regularly and for some duration in an organized way over the Internet through a common location or mechanism.
