The first wiki website (which will be called “wiki” from now on) was created by Cunningham in 1995, who described this kind of website as the simplest online database that could possibly work. The main concept behind a wiki website is to keep the website as simple as possible. Richardson (2006, p. 8) describes a wiki as a “collaborative web space where anyone can add content and anyone can edit content that has already been published.” Expanding this definition, wikis are collaboratively created websites in which users are able to create a series of web pages, edit and revise their own and others’ work, provide feedback, keep track of changes, and publish information online with minimal requirements on software and hardware and there is little need for user training (Leuf & Cunningham, 2001). Contents available on wikis are open for editing and feedback to all members at all times, while tracking other members’ contributions, and all the changes of contents can be done with ease.
