Wikipedia:What is a wiki

A wiki is a collection of interlinked web pages, each of which can be visited and edited by anyone. You can even edit the page you are reading right now: just click "Edit this page" above! (it really works?!)

This is a collaborative website, constantly expanding as new people add pages about their interests, comment on old pages, etc.
