<communications> A collaborative web site
comprised of the perpetual collective work of many authors.
Similar to a web log in structure and logic, a wiki allows anyone, using a browser interface, to edit, delete or modify content that has been placed on the web site including the work of other authors.
In contrast, a blog, typically authored by an individual, does not allow visitors to change the original posted material, only add comments.
The term can also refer to the software used to create the site.
Wiki wiki means "quick" in Hawaiian. The first wiki was created by Ward Cunnigham
