A wiki is a collaborative website, which people can build together. The concept was developed by WardCunningham. The name comes from 'wiki wiki', which is Hawaiian for 'quick'.
The site you are browsing right now is an example of a wiki. Since it is implemented in Squeak it is called a Swiki, which is short for 'Squeak Wiki'.
Another implementation of a wiki is SmallWiki
