Post #10: Why Wikipedia?

Why would anyone use Wikipedia as a reliable source of reference when anyone can alter what it states? I am really surprised to see such big names involved in altering information like Wikipedia. The problem isn't that information is changed from incorrect to correct, it is the information that is changed. I'm glad to see Virgil Griffith's WikiScanner keep up with who makes changes to what information and when. One has to remember that there may be a lot of unreliable sources on the internet and Wikipedia is one of them.
