开局一座山

A wiki, derived from the Hawaiian word "wikiwiki" meaning "quick," is a form of website that allows users to collaboratively edit and manage content directly through a web browser. Wiki sites typically contain multiple pages that can be edited by the public or restricted for internal organizational knowledge management. The core characteristic of wikis is their collaborative nature, emphasizing collective intelligence and contribution rather than a single author or leader. Unlike other web-based systems such as blogs or static site generators, wikis have no defined owner for content creation, and their structure emerges dynamically based on user needs. The first wiki was WikiWikiWeb, created by Ward Cunningham in 1995, which laid the foundation for subsequent wiki platforms. Wikis are widely used for knowledge management, community websites, intranets, and many other areas, with Wikipedia being the most famous example—a globally collaborative online encyclopedia. The open nature of wikis also makes them susceptible to vandalism, which is why they often adopt soft security approaches, making damage easy to undo rather than trying to prevent it. Many wikis keep all edit histories, enabling reversions to previous versions.
