A Wiki is a Web site that anyone can edit.

They work because there are more people that want to build something than
people that want to destroy things.

Two good ones are:
+ Wikipedia: An encyclopedia that anyone can help to build.
http://wikipedia.org/

+ IAwiki: A site where people contribute ideas about building good Web sites.
