Thing #16 - What's a Wiki?

I've been a little weary of wikipedia. That was the only wiki I knew of. Know I realize that wikis can be a powerful colloboration tool. It seems like bias and slants can be leveled out since wikis can be edited and contributed to by many users. That is a good thing. But what if the group of contributers is small? What if they are misinformed? I suppose that's where others come in to edit, but I could go around in circles about this. I keep thinking of the 30 Rock episode where the writers play a trick on one of the dimwitted actresses. They tell here to check wikipedia to research her role as Janice Joplin. They go in and edit content so that the actress believes the legendary rockstar speed walked everywhere and was allergic to denim.
