I've written a few Wikipedia articles. Even this limited experience was enough to turn me off the whole process.
Like a lot of people, I use Wikipedia to satisfy my curiosity.
I wouldn't cite it as a source in any kind of scholarly debate, and I wouldn't allow my students to cite it. In fact, I tell my first-year students that encyclopedias and websites of any kind are not acceptable sources for their research papers, as a way of forcing them to drag their lazy asses down to the library.
True story: one of my fellow professors had a student who plagiarized Wikipedia for his research paper--and then tried to get rid of the evidence of his plagiarism by editing the article.
My colleague found him out, of course, and gave him the zero he deserved. The student then went onto facebook and ranted about what an asshole my colleague was. My colleague's wife then brought this rant (and its author) to his attention
Do students think their professors have never heard of the internet, or something? We have, you know. Most of us, anyway.
Comedy gold right there. People have no work ethic or sense of pride anymore.
Anymore? people have *always* cheated, the net just made it easier. When I was still a prof, I had all sorts:
* The student who claimed that his paper wasn't plagiarism because he paid someone else to write it and he couldn't know the guy would sell the same paper more than once.
* A student who copied something directly out of my own papers
* A student who's assignment concluded with "more detail about this can be found on pg. 256"
* A student who forward me an e-mail with his "assignment" attached and at the bottom of the forward was the original email from a friend of his saying "this old assignment of mine should fit the topic".
Teaching is amazing for demonstrating how fucking dumb many clever people are...
