I recently read an article about "taking a stand against WIkipedia". The author, Scott Jaschik, wrote about Middlebury College and what the professors are doing about Wikipedia. They are banning students from citing Wikipedia for their papers. The purpose of this was to educate the students about what is wrong with Wikipedia and to proove that it is not all valid information.
Also, at University of California at Santa Barbara faculty stated that it "is not appropriate as the primary or sole reference for anything that is central to an argument, complex, or controversial".
While there are still faults with Wikipedia, it is not all bad. The site is maintained and edited constantly so inaccurate information is taken out. When a student is writing a paper or doing research, they just need to be careful and further investigate what they found on Wikipedia on other sites. They just can not use it as their only source.
