How fast is WIKI?!?

In my fellow classmate Alex's Blog he had a posting on a edit he made to the Metallica wikipedia article where he experimented on how long it would take for false information to be removed once submitted. I did a similar experiment for my own knowledge and it was pretty amazing for information that I actually thought was relevant was removed within 15 minutes of being editted and submitted. It is pretty amazing to see how fast they are monitoring these articles, but I guess they have to since Wikipedia is now used as a resource for information by everyone all over the internet. Keep up the good work WIKI!
