A wiki is not a guy from Star Wars

What I learned about document collaboration and wikis is that both allow the non html writing user to add content to the internet.

Document collaboration is just what it says: a number of people collaborating on a document.

Examples of sites on which you can collaborate are Buzzword, Zoho, Versionate, and Google Docs and oddly enough, SharePoint. Also due to launch this summer is TextFlow. Some collaborative writing projects are: Everything2, Galaxiki, and One Million Monkeys Typing.

Wikis, like Wikipedia are a collection of pages that anyone can modify or add to. I use Wikipedia often to get a general idea of something but because anyone can modify the content one can never be sure how accurate it is. In my estimation it is far too easy to add a little something of your own to a wiki if the wiki is presented as a research tool. Wikipedia is a one example of a wiki, as well as Wikibooks and Wikispaces, where you can start your own wiki.
