Though I have in fact been allowed to cite Wikipedia
by more than one
college professor. I usually approach the ones who disallow it to
find out their reasons and after dismantling their arguments with
"pro-Wikipedia propaganda" all I can see is some inexplicable
deep-seated hatred. Why I don't know.
Wikipedia isn't a good source for university level work. Either the
article you're using doesn't have references, in which case it's
completely unreliable, or it does have references, in which case you
should use them instead (there aren't many sources used as references
in Wikipedia articles which aren't accessible to university students).
Oh, and the admin bit can be quite useful outside of
Wikipedia. [snip]
I know - I've used it like that before as well! Never in an argument
with a lecturer, but in less formal arguments with various people.
