A wikiA Web site that can be modified by anyone, from directly within a Web browser (provided that user is granted edit access). is a Web site anyone can edit directly within a Web browser (provided the site grants the user edit access). Wikis derive their name from the Hawaiian word for “quick.” Ward Cunningham, the “wiki father” christened this new class of software with the moniker in honor of the wiki-wiki shuttle bus at the Honolulu airport. Wikis can be one of the speediest ways to collaboratively create content online.
Many popular online wikis serve as a shared knowledge repository in some domain. The largest and most popular wiki is Wikipedia, but there are hundreds of publicly accessible wikis that anyone can participate in, with examples ranging from Wine Wiki for oenophiles to Wookieepedia, the Star Wars wiki. Wikis can also be used for any collaborative effort—from meeting planning to project management. And in addition to the hundreds of public wikis, there are many thousand more that are hidden away behind firewalls, used as proprietary internal tools for organizational collaboration. Many wikis also serve as knowledge management systems that act as a sort of collective corporate memory that’s vital for sharing skills, learning, and preserving expertise even when employees leave the firm.
Want to add to or edit a wiki entry? On most sites you just click the “Edit” link. Wikis support what you see is what you get (WYSIWYG)A phrase used to describe graphical editing tools, such as those found in a wiki, page layout program, or other design tool. editing that, while not as robust as traditional word processors, is still easy enough for most users to grasp without training or knowledge of arcane code or markup language. Users can make changes to existing content and can easily create new pages or articles and link them to other pages in the wiki. Wikis also provide a version history. Click the “History” link on Wikipedia, for example, and you can see when edits were made and by whom. This feature allows the community to roll backThe ability to revert a wiki page to a prior version. This is useful for restoring earlier work in the event of a posting error, inaccuracy, or vandalism. a wiki to a prior page, in the event that someone accidentally deletes key info, or intentionally defaces a page.
Wikis are available both as software (commercial as well as open source varieties) that firms can install on their own computers and as hosted online services (subscription or ad-supported) where software and content are housed by third parties that run the technology for wiki users. Since wikis can be started without the oversight or involvement of a firm’s IT department, their appearance in organizations often comes from grassroots user initiative.
As with blogs, a wiki’s features set varies depending on the specific wiki tool chosen, as well as administrator design, but most wikis support the following key features:
Jump-starting a wiki can be a challenge, and an underused wiki can be a ghost town of orphan, out-of-date, and inaccurate content. Fortunately, once users see the value of wikis, use and effectiveness often snowballs. The unstructured nature of wikis are also both a strength and weakness. Some organizations employ wikimastersIndividuals often employed by organizations to review community content in order to delete excessive posts, move commentary to the best location, and edit as necessary. to “garden” community content: “prune” excessive posts, “transplant” commentary to the best location, and “weed” as necessary. Wikipatterns.com offers a guide to the stages of wiki adoption and a collection of community-building and content-building strategies.
The larger and more active a wiki community, the more likely it is that content will be up to date and that errors or vandalism will be quickly corrected (again, we see the influence of network effects, where products and services with larger user bases become more valuable). At Wikipedia, for example, griefersInternet vandal and mischief maker; also sometimes referred to as a troll. and partisans regularly alter pages (in one noteworthy stretch, the page of former U.S. President Jimmy Carter was regularly replaced with a photo of a “scruffy, random unshaven man with his left index finger shoved firmly up his nose.”)D. Pink, “The Book Stops Here,” Wired, March 2005. But the Wikipedia community is so large and attentive that such changes are often recognized in seconds and rolled back, and mischief makers soon give up and move on. Several studies have shown that large community wiki entries are as or more accurate than professional publication counterparts.S. Robert Lichter, Are Chemicals Killing Us? Statistical Assessment Service, May 21, 2009; J. Kane, R. Fichman, J. Gallaugher, and J. Glaser, “Community Relations 2.0,” Harvard Business Review, November 2009.
Wikis can be vital tools for collecting and leveraging knowledge that would otherwise be scattered throughout an organization; reducing geographic distance; removing boundaries between functional areas; and flattening preexisting hierarchies. Companies have used wikis in a number of ways:
When brought outside the firewall, corporate wikis can also be a sort of value-generation greenhouse, allowing organizations to leverage input from their customers and partners:
Not only is the nonprofit Wikipedia, with its enthusiastic army of unpaid experts and editors, replacing the three-hundred-year reference reign of Encyclopedia Britannica, Wikipedia entries can impact nearly all large-sized organizations. Wikipedia is the go-to, first-choice reference site for a generation of “netizens,” and Wikipedia entries are invariably one of the top links, often the first link, to appear in Internet search results.
This position means that anyone from top executives to political candidates to any firm large enough to warrant an entry has to contend with the very public record of Wikipedia. In the same way that firms monitor their online reputations in blog posts and Twitter tweets, they’ve also got to keep an eye on wikis.
But firms that overreach and try to influence an entry outside of Wikipedia’s mandated neutral point of view (NPOV)An editorial style that is free of bias and opinion. Wikipedia norms dictate that all articles must be written in NPOV., risk a backlash and public exposure. Version tracking means the wiki sees all. Users on computers at right-leaning Fox News were embarrassingly caught editing the wiki page of the lefty pundit and politician Al Franken (a nemesis of Fox’s Bill O’Reilly);A. Bergman, “Wikipedia Is Only as Anonymous as your I.P.,” O’Reilly Radar, August 14, 2007. Sony staffers were flagged as editing the entry for the Xbox game Halo 3;I. Williams, “Sony Caught Editing Halo 3 Wikipedia Entry,” Vnunet.com, September 5, 2007. and none other than Wikipedia founder Jimmy Wales was criticized for editing his own Wikipedia biographyE. Hansen, “Wikipedia Founder Edits Own Bio,” Wired, December 19, 2005.—acts that some consider bad online form at best, and dishonest at worst.
One last point on using Wikipedia for research. Remember that according to its own stated policies, Wikipedia isn’t an original information source; rather, it’s a clearinghouse for verified information. So citing Wikipedia as a reference usually isn’t considered good form. Instead, seek out original (and verifiable) sources, such as those presented via the links at the bottom of Wikipedia entries.
