Guest post from Annie and Molly Fortnow
Our teachers used to tell us not to use Wikipedia because anybody can edit it and therefore it isn't trustworthy. A couple of years ago we decided to test it out. [Not with my knowledge - Lance]
We went to the Cow page but it was locked showing that some subjects can't be edited. We then proceeded to the Grapes page which was unlocked. So we added to the bottom: "Grapes are good. Nerds are cows." We immediately got a message popping up on the screen that said something like "That's an inappropriate remark. It's being deleted. You are getting a warning."
Now we know that if someone edits Wikipedia with something silly it will always be edited back. So, now we trust Wikipedia and use it often. Every time one of our friends asks us why we use Wikipedia we tell this story and everyone always believes us. Now all our friends trust Wikipedia too.
