I have also made a very interesting discovery about wikipedia. I have always dismissed it as unreliable, no matter how many citations there appear to be. Lately, though, I have had to revise my opinion. There is actually an inverse relationship between how complex a topic is and how inaccurate its wikipedia entry is.
That is, the more mainstream and well-known the topic, the more likely wikipedia is to be inaccurate, apocryphal, or flat-out wrong. Conversely, the more complex the topic, the more likely it is to be completely accurate and fully comprehensive.
