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:** 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:** 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:** Dedicated discussion pages enable contributors to coordinate and discuss content. Typical uses - Community-driven knowledge bases (for example, Wikipedia) - Project documentation and internal company knowledge repositories - Collaborative writing and shared note-taking - School and instructional projects Pros - **Fast collaboration:** Multiple people can add and refine content quickly. - **Openness:** Edit histories and talk pages reveal how content decisions were made. - **Expandable:** They scale organically as users add more pages and topics. Limitations - **Vandalism and false information:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Articles can differ greatly in depth, tone, and reliability. - **Organizational issues:** Lack of structure or rules can lead to disorganization and conflicts. Notable example - **Wikipedia** — the largest example, maintained by the Wikimedia Foundation and contributed to by volunteers worldwide.</p>
