This is enough to make a Librarian weep.

I have just introduced a friend to Wikipedia. He was impressed but dubious about the concept, so he decided to test it. He found a topic he knew something about that didn't have an entry and made one up, which was totally false. He then went to Yahoo Q&A and asked something about the same topic. Low and behold, the answer he got back was the same rubbish he'd posted on Wikipedia.

It's on the Internet so it must be true? Discuss.
