Wiki: Pedia

<p>A wiki is a website designed for collaborative editing, letting many people create, update, and organize content directly in a web 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. Key features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** All edits are stored with timestamps and the author’s name or IP. - **Interlinking:** Links between pages are simple to create, helping build connected content. - **Lightweight markup:** Pages are typically formatted with lightweight markup like WikiText or Markdown. - **Permission settings:** Access controls vary — from fully open editing to permissions for certain users or groups. - **Discussion pages:** Separate talk pages allow contributors to discuss edits and structure. Frequent uses - Crowd-sourced knowledge resources (e.g., Wikipedia) - Project docs and corporate knowledge repositories - Collaborative writing and shared note-taking - Educational and classroom projects Pros - **Fast collaboration:** Contributors can rapidly create and improve content. - **Openness:** Transparency through revision histories and discussions. - **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:** Content quality may vary widely between pages. - **Organizational issues:** Without clear governance, content may become fragmented or disputed.
