Common uses included project communication, intranets, and documentation, initially for technical users. Cunningham’s system was inspired by his having used Apple’s hypertext software HyperCard, which allowed users to create interlinked “stacks” of virtual cards. It is typically possible for users of a wiki to create links to pages that do not yet exist, as a way to invite the creation of those pages. Some wiki implementations attempt to improve the display of camel case page titles and links by reinserting spaces and possibly also reverting to lower case, but this simplistic method is not able to correctly present titles of mixed capitalization. While this system made it easy to link to pages, it had the downside of requiring pages to be named in a form deviating from standard spelling, and titles of a single word required abnormally capitalizing one of the letters (e.g. “WiKi” instead of “Wiki”).

• Trolling and cybervandalism on wikis, where content is changed to something deliberately incorrect or a hoax, offensive material or nonsense is added, or content is maliciously removed, can be a major problem.
• On implementations where an administrator is able to restrict editing of a page or group of pages to a specific group of users, they may have the option to prevent anonymous editing while allowing it for registered users.
• The software which powers a wiki may be implemented as a series of scripts which operate an existing web server, a standalone application server that runs on one or more web servers, or in the case of personal wikis, run as a standalone application on a single computer.
• A WikiNode is a page on a wiki which describes and links to other, related wikis.
• A city wiki or local wiki is a wiki used as a knowledge base and social network for a specific geographical locale.
• English Wikipedia has been characterized as having less cultural bias than other language editions due to its broader editor base.

Some companies use wikis as their collaborative software and as a replacement for static intranets, and some schools and universities use wikis to enhance group learning. In the early 2000s, wikis were increasingly adopted in enterprise as collaborative software. Such links are usually differentiated visually in some fashion, such as being colored red instead of the default blue, which was the case in the original WikiWikiWeb, or by appearing as a question mark next to the linked words. This syntax was adopted by a number of later wiki engines.
Traditionally, wikis offer free navigation between their pages via hypertext links in page text, rather than requiring users to follow a formal or structured navigation scheme. These stores are typically presented for each page in a list, called a “log” or royaldogs casino “edit history”, available from the page via a link in the interface. Some wikis present users with an edit button or link on the page being viewed. Wikipedia is not a single wiki but rather a collection of hundreds of wikis, with each one pertaining to a specific language, making it the largest reference work of all time.

Version history

Some wiki implementations keep a record of changes made to wiki pages, and may store every version of the page permanently. WYSIWYG editors may not provide all the features available in wiki markup, and some users prefer not to use them, so a source editor will often be available simultaneously. The syntax and features of wiki markup languages for denoting style and structure can vary greatly among implementations.

External links

• A person willing to maintain pages will be alerted of modifications to them, allowing them to verify the validity of new editions quickly.
• Some wikis may be subject to external structures of governance which address the behavior of persons with access to the system, for example in academic contexts.
• The syntax used to create internal hyperlinks varies between wiki implementations.
• A typical wiki contains multiple pages that can either be edited by the public or any organization.
• It was created by Jimmy Wales and Larry Sanger on 15 January 2001, as Wikipedia’s first edition.
• WikiNode networks act as webrings which may be navigated from one node to another to find a wiki which addresses a specific subject.
• These stores are typically presented for each page in a list, called a “log” or “edit history”, available from the page via a link in the interface.

A notable discussion within the English Wikipedia community concerns the preference for national variety of the English language, particularly American English and British English. Conflicts of interest arising from corporate campaigns to influence content have also been highlighted. Concerns have also been raised about systemic bias along gender, racial, political, corporate, institutional, and national lines. Critics have questioned its factual reliability, the readability and organization of its articles, the lack of methodical fact-checking, and its political bias. It was created by Jimmy Wales on 4 December 2003 as an extension of the decision-making power he had formerly held as owner of the site.
The trend analysis published in The Economist presents Wikipedia in other languages (non-English Wikipedia) as successful in retaining their active editors on a renewable and sustained basis, with their numbers remaining relatively constant at approximately 42,000. The Economist reported that the number of contributors with an average of five or more edits per month was relatively constant since 2008 for Wikipedia in other languages at approximately 42,000 editors within narrow seasonal variances of about 2,000 editors up or down. These ideas include “featured articles”, the neutral-point-of-view policy, navigation templates, the sorting of short “stub” articles into sub-categories, dispute resolution mechanisms such as mediation and arbitration, and weekly collaborations. Editors of the English Wikipedia have pioneered some ideas as conventions, policies or features which were later adopted by Wikipedia editions in some of the other languages. The English Wikipedia currently has 54,334,804 registered accounts of which 811 are administrators. English Wikipedia has been characterized as having less cultural bias than other language editions due to its broader editor base.

The range of quality classes begins with “Stub” (very short pages), followed by “Start”, “C” and “B” (in increasing order of quality). The study identified the most disputed entries on the English Wikipedia as George W. Bush, anarchism, Muhammad, list of WWE personnel, global warming, circumcision, United States, Jesus, race and intelligence, and Christianity. In contrast, articles on other languages’ Wikipedias often focus on regional issues.
In that implementation, link terms were wrapped in a double set of square brackets, for example Kingdom of France. To avoid this problem, the syntax of wiki markup gained free links (called wikilinks), wherein a term in natural language could be wrapped in special characters to turn it into a link without modifying it. For example, “Kingdom of France” as a page title would be written as “KingdomOfFrance”, and displayed as “Kingdom Of France”. Beginning with WikiWikiWeb in 1995, most wikis used camel case to name pages, which is when words in a phrase are capitalized and the spaces between them removed. The syntax used to create internal hyperlinks varies between wiki implementations.

In the mid-2000s, the increasing trend among industries toward collaboration placed a heavier impetus upon educators to make students proficient in collaborative work, inspiring even greater interest in wikis being used in the classroom. In addition to using the approach of soft security for protecting themselves, larger wikis may employ sophisticated methods, such as bots that automatically identify and revert vandalism. “Edit war” redirects here; not to be confused with Edit conflict.
As most wikis allow the creation of hyperlinks to other sites and services, the addition of malicious hyperlinks, such as sites infected with malware, can also be a problem. Some wikis may be subject to external structures of governance which address the behavior of persons with access to the system, for example in academic contexts. Some wiki software allows administrators to prevent pages from being editable until a decision has been made on what version of the page would be most appropriate. Trolling and cybervandalism on wikis, where content is changed to something deliberately incorrect or a hoax, offensive material or nonsense is added, or content is maliciously removed, can be a major problem. High editorial standards in medicine and health sciences articles, in which users typically use peer-reviewed journals or university textbooks as sources, have led to the idea of expert-moderated wikis. Proponents maintain that these issues will be caught and rectified by a wiki’s community of users.
