Thanks, aimless, you said it better--and in a lot less words--than I did!

Sandia, for your information, most university professors will not accept wikipedia as a reference, and with good reason. The articles there are only as good as the generally anonymous people who contribute them, whose expertise in the areas about which they write is completely unverified.

The whole problem with non-peer-reviewed articles is that the authors can pick and choose their sources without anyone's being the wiser. It has happened with peer review, too, but it's a lot harder to get away with.
