I'm an Assistant Professor of Political Science at a small liberal arts college. I started monitoring Wikipedia because so many of my students were using it as a starting point (and sometimes as the final word) in their research. While I do not let students cite wiki in formal papers, I do recognize that they often use wiki to find other sources. Therefore, I occassionally edit wiki--mostly politically relevant articles. I also encourage my students to edit wiki (responsibly) using the information they learn in class.
