Wikipedia

So I had heard of this website "Wikipedia" a couple times before my brother explained to me what it actually was a couple weeks ago.

Wikipedia is an online encyclopedia. What is neat about it is that anyone can edit any article. Because it has a large enough user base (as well as a handful of editors), any bogus information will be edited out rather quickly.

If you look up Wikipedia on Wikipedia, you get a more in depth description, including:
"Almost all visitors may edit Wikipedia's articles and have their changes instantly displayed. Wikipedia is built on the belief that collaboration among users will improve articles over time, in much the same way that open-source software develops. Its authors need not have any expertise or formal qualifications in the subjects which they edit, and users are warned that their contributions may be "edited mercilessly and redistributed at will" by anyone who so wishes."

Anyway, it's definitely a cool resource. Find something you know a lot about, and add some info that's not there...
