Snopes is not a good source for technical advice. If you look at the way Snopes words most of their answers, there is a lot of vague wording. That's because Snopes doesn't really bother to investigate issues beyond being true, false or accurate. In true liberal fashion, Snopes does like to sound more authoritive then it is. In this case, the only thing that is truly accurate from the Snopes article on this is that it is "true".
