Yesterday while editing a Wikipedia article and babysitting my nieces, they came up to see what I was doing. They both were impressed that I was editing an article (theyr'e 10 and 12, and highly web supervised), and wanted to see how it worked, and wanted to know how I knew what to write. The older girl told me that they get to use Wikipedia at school but if they "vandal" it they'll get in trouble.
