Wikipedia might not be the most trusted source. Why? Because anyone can edit it. Therefore it can easily be wrong.
However, by the same token, it's more likely to be right. Why? Because anyone can edit it. If someone puts something wrong in, anyone can change it back to what is right.
I frequently tell people who try to argue that Wikipedia is wrong, that if that's the case, they should edit it, and if the edit stands (IE if nobody contests it, or, if they win such a contention) then I will back down and accept their position.
