Wikipedia? Don't even think about it!

In academic circles, Wikipedia is considered an unreliable source because of the fluid nature of wikis.  Information may be incorrect and pages can change at any time.

Mr. Hatten's English 10 rule:

If you use wikipedia as a source (either cited or uncited) it will result in an automatic "F" grade on your paper and a zero score. 

Use wikipedia for casual research, but be careful to not use it in academic research.
