WikiWikiWeb is the first wiki engine and wiki forum ever. The wiki engine has been developed since 1994 by Howard Cunningham. The wiki forum was inaugurated on March 25, 1995.
Both the wiki engine and the wiki forum are called WikiWikiWeb. Abbreviated variants of the name WikiWikiWeb are WikiWiki and Wiki. Howard Cunningham named WikiWikiWeb after Wiki Wiki, which is a line of shuttle buses that runs between terminals at Honolulu International Airport. The name of the shuttle line is derived from the Hawaiian-language expression wiki wiki, which is a word reduplication of wiki, a word that means "fast". The reduplication wiki wiki is used to emphasize wiki, so wiki wiki could be translated as "faster than fast".
The tag line of WikiWikiWeb is "PeopleProgrammingAndPatterns". The original purpose of WikiWikiWeb was to document programming patterns, especially for members of the Patterns mailing list, which is now operated by the Hillside Group, and for people who attended the Patterns Languages of Programs Conference (PLoP) and the Conference on Object Oriented Programming Systems Languages and Applications (OOPSLA).
However, around 1996 to 1998 approximately, discussion of extreme programming (XP) became more popular, and the first members of WikiWikiWeb, who preferred to discuss patterns, started emigrating. Some of them later complained about missing wiki before XP.
Many former regular users of WikiWikiWeb have complained that the discussion on WikiWikiWeb has deteriorated since about 1999 or 2000, and some of them have described that deterioration as the heat death of Wiki.
