Wikipedia: The know-it-all Web site

CNN Has A Story featuring Wikipedia, they describe as a free encyclopedia logging over 140,000 articles sent in by people from all over the world.

What is unique is that, not only is it free and easy to use, it also allows users to go in and edit an entry.

Wiki comes from the Hawaiian term for “quick.” And like a Web log, it’s a fast and easy way to publish online. But unlike a Web log, which typically publishes a single voice, a Wiki is the collective work of many writers.
