Wikis are becoming popular.  They are a form of informal community learning that puts content creation in the hands of the masses.  So, I'm wondering if Wikis will catch on in corporate learning.  And should they be considered e-Learning?

According to the most used Wiki in the world, the definition of a wiki is:

A wiki is a type of website that allows users to add and edit content and is especially suited for collaborative authoring.

The term wiki also sometimes refers to the collaborative software itself (wiki engine) that facilitates the operation of such a website.

In essence, a wiki is a simplification of the process of creating HTML pages combined with a system that records each individual change that occurs over time, so that at any time, a page can be reverted to any of its previous states. A wiki system may also provide various tools that allow the user community to easily monitor the constantly changing state of the wiki and discuss the issues that emerge in trying to achieve a consensus about the wiki content.

Some wikis, notably Wikipedia, allow almost completely unrestricted access so that people are able to contribute to the site without necessarily having to undergo a process of 'registration' as had usually been required by various other types of interactive web sites such as Internet forums or chat sites.

The WikiWikiWeb is named after the "Wiki Wiki" line of Chance RT-52 buses in Honolulu International Airport. The name is based on the Hawaiian term wiki, meaning "quick", "fast", or "to hasten" (Hawaiian dictionary). Sometimes wikiwiki (or Wikiwiki) is used instead of wiki (Hawaiian dictionary).

Wiki is sometimes interpreted as the backronym for "What I know is", which describes the knowledge contribution, storage and exchange function.
