Changes

''Wiki'' (with an upper case 'W') and ''WikiWikiWeb'' are both used to specifically refer to the Portland Pattern Repository, the first-ever wiki. This usage's proponents suggest a lower-case 'w' for wikis in general. ''Wiki wiki'' comes from the Hawaiian term for "quick" or "super-fast."; sometimes, '''wikiwiki''' or '''WikiWiki''' or '''Wikiwiki''' are used instead of ''wiki..''
