A virtual community, e-community or online community is a group of people that primarily interact via some form of mechanism such as letters, telephone, email or the Internet rather than face to face. If the mechanism is a computer network, it is called an online community. Virtual and online communities have also become a supplemental form of communication between people who know each other primarily in real life. A computer-mediated community (CMC) uses social software to regulate the activities of participants. Significant socio-technical change has resulted from the proliferation of Internet-based social networks.

Overview

A virtual community is a social network with a common interest, idea, task or goals that interact in a virtual society across time, geographical and organizational boundaries and is able to develop personal relationships.

Different virtual communities have different levels of interaction and participation among their members. This ranges from adding comments or tags to a blog or message board post to competing against other people in online video games such as MMORPGs. Not unlike traditional social groups or clubs, virtual communities often divide into cliques or even separate to form new communities. Author Amy Jo Kim points out a potential difference between traditional structured online communities (message boards, chat rooms, etc), and more individual-centric, bottom-up social tools (blogs, instant messaging buddy lists), and suggests the latter are gaining in popularity.

Today, virtual community or online community is used for a variety of social groups interacting via the Internet. It does not necessarily mean that there is a strong bond among the members, although Rheingold mentions that virtual communities form "when people carry on public discussions long enough, with sufficient human feeling, to form webs of personal relationships". An email distribution list may have hundreds of members and the communication which takes place may be merely informational (questions and answers are posted), but members may remain relative strangers and the membership turnover rate could be high. This is in line with the liberal use of the term community.

Virtual communities may synthesize Web 2.0 technologies with the community, and therefore have been described as Community 2.0, although strong community bonds have been forged online since the early days of USENET. Virtual communities depend upon social interaction and exchange between users online.

The ability to interact with like-minded individuals instantaneously from anywhere on the globe has considerable benefits, but virtual communities have bred some fear and criticism. Virtual communities can serve as dangerous hunting grounds for online criminals, such as identity thieves and stalkers, with children particularly at risk. Others fear that spending too much time in virtual communities may have negative repercussions on real-world interaction (see Internet addiction disorder).

The explosive diffusion of the Internet since the mid-1990s has also fostered the proliferation of virtual communities. The nature of those communities is diverse, and the benefits that Rheingold envisioned are not necessarily realized, or pursued, by many. At the same time, it is rather commonplace to see anecdotes of someone in need of special help or in search of a community benefiting from the use of the Internet.

Membership life cycle for virtual communities

A membership life cycle for online communities was proposed by Amy Jo Kim (2000). It states that members of virtual communities begin their life in a community as visitors, or lurkers. After breaking through a barrier, people become novices and participate in community life. After contributing for a sustained period of time they become regulars. If they break through another barrier they become leaders, and once they have contributed to the community for some time they become elders. This life cycle can be applied to many virtual communities, most obviously to bulletin boards, but also to blogs and wiki-based communities.

Legitimate peripheral participation

Lave and Wengers' theories on situated cognition can illustrate the cycle of how users become incorporated into virtual communities using the principles of legitimate peripheral participation. They define five types of trajectories amongst a learning community:

The following shows the correlation between the learning trajectories and Web 2.0 community participation.

Learning trajectory — online community participation

Example – YouTube

Peripheral (Lurker) – Observing the community and viewing content. Does not add to the community content or discussion The user occasionally goes onto YouTube.com to check out a video that someone has directed them to.

Inbound (Newbie) – Just beginning to engage the community. Starts to provide content. Tentatively interacts in a few discussions. The user comments on other user’s videos. Potentially posts a video of their own.

Insider (Regular) – Consistently adds to the community discussion and content. Interacts with other users. Regularly posts videos. Either videos they have found or made themselves. Makes a concerted effort to comment and rate other user’s videos.

Boundary (Moderator/ Expert) – Recognized as a veteran participant. Connects with regulars to make higher concepts ideas. Community grants their opinion greater consideration. The user has become recognized as a contributor to watch. Possibly their videos are podcasts commenting on the state of YouTube and its community. The user would not consider watching another user’s videos without commenting on them. Will often correct a user in behavior the community considers inappropriate. Will reference other user’s videos in their comments as a way to cross link content.

Outbound (Legacy) – Leaves the community for a variety of reasons. Interests have changed. Community has moved in a direction that doesn’t agree with. Lack of time. User got a new job that takes up too much time to maintain a constant presence in the community. That and the YouTube culture seems to be drifting to a corporate commercial endorsement model rather than a social, grassroots platform that it once was.

Sense of community

People, in general, are fairly social beings and it is motivating to many people to receive direct responses to their contributions. Most online communities enable this by allowing people to reply back to contributions (i.e. many Blogs allow comments from readers, one can reply back to forum posts, etc). Again, using Amazon.com, other users can rate whether one's product review was helpful or not. Granted, there is some overlap between increasing reputation and gaining a sense of community. However, it seems safe to say that there are some overlapping areas between all four motivators.

The Internet forum

An Internet forum is a web application for holding discussions and posting user generated content. Internet forums are also commonly referred to as web forums, message boards, discussion boards, (electronic) discussion groups, discussion forums, bulletin boards, fora (the Latin plural) or simply forums. The terms "forum" and "board" may refer to the entire community or to a specific sub-forum dealing with a distinct topic. Messages within these sub-forums are then displayed either in chronological order or as threaded discussions.

Such forums perform a function similar to that of the dial-up bulletin board systems and Internet newsgroups that were numerous in the 1980s and 1990s. Early web-based forums such as UBB.classic date back as far as 1996. A sense of virtual community often develops around forums that have regular users. Technology, computer games and/or video games, fashion, religion, and politics are popular areas for forum themes, but there are forums for a huge number of different topics. Internet slang and image macros popular across the internet are abundant and most widely used in internet forums.
