A wiki is a website that allows visitors to add, remove, edit and change content. It also allows for linking among any number of pages. This ease of interaction and operation makes a wiki an effective tool for mass collaborative authoring. The term wiki also can refer to the collaborative software itself (wiki engine) that facilitates the operation of such a site, or to certain specific wiki sites, including the computer science site (the original wiki) WikiWikiWeb and online encyclopedias such as Wikipedia.

WHY IT’S COOL
First of all, you can develop a “wiki” web site for free. Even the paid services are pretty cheap.

Second, it’s easy to learn and do.

Third, you can use wiki technology to collaborate with colleagues located anywhere. Imagine collaborating on a document. You all sign in and can change the document right then and there, together. Everyone sees the changes in real time (real time = “right away!”)

Fourth, you can use wiki to create public sites (like Wikipedia). Such sites allow anyone and everyone to participate in the site, offering their opinions, ideas, reactions, etc.
