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. Main features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** Creating links among pages is straightforward, which helps interconnect content. - **Lightweight markup:** Formatting is usually handled by lightweight markup languages (e.g., WikiText or Markdown). - **Permission settings:** Access controls vary — from fully open editing to permissions for certain users or groups. - **Discussion pages:** Dedicated discussion pages enable contributors to coordinate and discuss content. Frequent uses - Community knowledge bases such as Wikipedia - Internal documentation and company knowledge bases - Group writing and collaborative note-taking - Educational and classroom projects Pros - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Transparency through revision histories and discussions. - **Expandable:** Wikis can grow naturally as contributors add new topics. Cons - **Vandalism and false information:** Open contribution can result in deliberate or accidental misinformation. - **Inconsistent quality:** Articles can differ greatly in depth, tone, and reliability. - **Organizational issues:** Without clear governance, content may become fragmented or disputed. Example - **Wikipedia** — the largest example, maintained by the Wikimedia Foundation and contributed to by volunteers worldwide.</p>
