Wikis as tools for collaboration

Tim Berners-Lee, the inventor of the World Wide Web, envisioned it as a place where “people can communicate … by sharing their knowledge in a pool … putting their ideas in, as well as taking them out” (Berners-Lee, 1999). For much of its first decade, the Web was, however, primarily a place where the majority of people took ideas out rather than putting them in. This has changed. Many “social software” services now exist on the Web to facilitate social interaction, collaboration and information exchange. This article introduces wikis, jointly edited Web sites and Intranet resources that are accessed through web browsers. After a brief overview of wiki history, we explain wiki technology and philosophy, provide an overview of how wikis are being used for collaboration, and consider some of the issues associated with management of wikis before considering the future of wikis. In 1995, an American computer programmer, Ward Cunningham, developed some software to help colleagues quickly and easily share computer programming patterns across the Web. He called the software WikiWikiWeb, after the “Wiki Wiki” shuttle bus service at Honolulu International Airport (Cunningham, 2003). As interest in wikis increased, other programmers developed wiki software, most of it (like WikiWikiWeb) open source. Although wiki software was relatively simple by industry standards, some technical knowledge was required to install, maintain and extend the “wiki engines.” Contributors needed to learn and use a markup language to edit pages, and even if the markup languages were often simpler than HTML, non-technical users did not find these early wikis compelling. In the early years of the twenty-first century, a number of developments led to more widespread use of wikis. Wiki technology became simpler to install and use, open source software was improved, and commercial enterprise-grade wiki software was released. The not insignificant issues associated with attracting and managing a community of people who use a wiki to share their knowledge were discussed in forums such as MeatballWiki (http://www.usemod.com/cgibin/ mb.pl?action=browse&id=MeatballWiki&ol did=FrontPage). The public’s attention was drawn to wikis following the launch, in January 2001, of the publicly written Web-based encyclopedia, Wikipedia (www.wikipedia.org). And wiki hosting services and application service providers (ASPs) were established to enable individuals and organizations to develop wikis without the need to install and maintain wiki software themselves. By July 2006, nearly 3,000 wikis were indexed at the wiki indexing site www.wikiindex. org, popular wiki hosting services such as Wikia (www.wikia.org) and seedwiki (www.seedwiki. org) hosted thousands of wikis between them, and Wikipedia had more than four and a half million pages in over 100 languages. Moreover, wikis were increasingly being used in less public ways, to support and enable collaboration in institutions ranging from businesses to the public service and not-for-profit organizations.
