Other online communities allow a wide variety of professionals to come together to share thoughts, ideas and theories.
It has been argued that the technical aspects of online communities, such as whether pages can be created and edited by many, as is the case with wikis including Wikipedia, or whether only certain users can post entries and edit them, as is the case with most blogs, can place online communities into stylistic categories.People may also join online communities through video games, blogs and virtual worlds.Constance Elise Porter from the University of Notre Dame in a paper entitled A Typology of Virtual Communities: A Multi-Disciplinary Foundation for Future Research offers this definition: "a virtual community is defined as an aggregation of individuals or business partners who interact around a shared interest, where the interaction is at least partially supported and/or mediated by technology and guided by some protocols or norms." The idea of a community is not a new concept.Online activity by fans seem to have had a noticeable influence on the plot and direction of the season opening episode.Mark Lawson of The Guardian recounts how fans have, to a degree, directed the outcome of the events of the episode.Many researchers have used ethnography to attempt to understand what people do in online spaces, how they express themselves, what motivates them, how they govern themselves, what attracts them, and why some people prefer to observe rather than participate.
There is a set of values known as netiquette (or Internet etiquette) to consider as an online community develops.
Some of these values include: opportunity, education, culture, democracy, human services, equality within the economy, information, sustainability, and communication.
Online communities may be used as calendars to keep up with events such as upcoming gatherings or sporting events. Many online communities relating to health care help inform, advise and support patients and their families.
What makes these communities bond is "love" of something as demonstrated by members who go out of their way to help without any financial interest.
A 2001 Mc Kinsey & Company study showed that only 2% of transaction site customers returned after their first purchase, while 60% of new online communities users began using and visiting the sites regularly after their first experiences.
On the telephone, in ham radio and in the online world, social interactions no longer have to be based on proximity; instead they can literally be with anyone anywhere.
