Wikis: What are they? Why are they useful?

Wikis are all the rage. What are they? Why are people so excited about them? How can I start one? Why would I want to?

Read a basic description of wikis here:

When you're done there, you can find a lot more information at the oh-so-helpful site, Howstuffworks.com: http://computer.howstuffworks.com/wiki.htm.

Feel like trying your hand at collaborating via Wiki? Here are some websites that let you create your own for free. Once you've created it, consider sharing the link in your personal journal or post it in Sharing Solutions and inviting others to work with you.
