Here’s a good overview article from PC Mag focusing on wikis as collaboration tools:
If your project team needs to develop a proposal together, or your school friends want to jointly create a reunion Web site, you don’t need to purchase expensive collaboration software. Instead, you can create a wiki. Anyone who has spent time at Wikipedia ( http://en.wikipedia.org ) or other wikis (the name is derived from a Hawaiian word for “quick”) knows them as sites where users can both add content, using any Web browser, and edit other people’s content. Most wiki engines provide basic features such as creating and deleting pages, bullet lists, headings, emphasis, indentation, and horizontal lines. And you can find plenty of information on the Web about text formatting rules and wiki style and structure guides.
Note to self: when that bewildered look appears on a person’s face when I say wiki, direct that person here.
