Collective IQ: Wikis Bring the World Together

No one likes a know-it-all. But occasionally, you learn things in life that ring true. If you were to put all of those random and not-so-random bits and pieces of priceless knowledge and wisdom together in one place, you'd have a knowledge resource of tremendous value.

That's the goal of a wiki--an open online encyclopedia of sorts that remains continuously under development by anyone who cares to contribute. One of the largest and most fascinating is Wikipedia.org (see FIGURE 11), which, not surprisingly, contains the most detailed history of and guide to wikis anywhere. For a list of nearly every wiki on the Web, check out WorldWideWiki's SwitchWiki site.

If you have a yen to work on your own wiki, you can practice editing one at Meatball's SandBox site, and once you're ready to leave the sandbox, you can go out and tell the world what you really think.
