“A wiki is a collaborative website where users can create and edit pages. Wikis fall conceptually under the broad concept of content management, and you could certainly use your existing CMS to create a wiki-like site. However, wikis bring unique characteristics that differentiate them from a run-of-the-mill content management systems.
Wikis emphasize ease of content creation. This simplicity comes mostly from many sources:
- A wiki markup language that provides a short-hand way of formatting text and linking documents.
- The ability of users to create and edit pages directly and independently.
- A bottom-up approach to site structure and navigation.
- Very simple templating.
- A conscious decision to eschew workflow or even simple approval steps.”
