Wiki: Pedia

<p>A wiki is a web platform that enables multiple users to collaboratively create, edit, and arrange content through a browser. Wikis prioritize ease of use and openness: pages can be added or changed without technical expertise, and most track every edit so changes can be reviewed or undone. Common features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** Links between pages are simple to create, helping build connected content. - **Lightweight markup:** Simple markup languages (such as WikiText or Markdown) are used to format pages. - **Permission settings:** Wikis may allow public editing or restrict changes to registered or authorized users. - **Discussion pages:** Separate talk pages allow contributors to discuss edits and structure. Common uses - Community knowledge bases such as Wikipedia - Project docs and corporate knowledge repositories - Group writing and collaborative note-taking - Educational and classroom projects Benefits - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** They scale organically as users add more pages and topics. Cons - **Vandalism and false information:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Entries may vary in accuracy, style, and completeness. - **Organizational issues:** Poor coordination or governance can cause content fragmentation and disputes.
