A faculty member just emailed me to let me know about RateMyProfessor (http://ratemyprofessors.com), a site where students can post ratings and comments about their professors to help other students decide which courses/faculty to take. (The most notorious aspect of this site is that students can also assign faculty "chili peppers," which means they are hot--although I have spoken to some students who interpret that as more like cool/hip rather than physically attractive.)
I personally always checked my ratings when I was teaching at Loudoun (my favorite comment was the student who complained that I was not aware that my class was an ELECTIVE, "not BIO or something!"). I also know deans and provosts who use the site to check up on their faculty. Although many of us are a bit leery of student comments, especially on a site like this, I find that the general trend of the comments is usually pretty accurate, both about one's strengths and one's weaknesses.
At any rate, I'm passing it along, since if one person wasn't aware of the site, she was probably not the only one! You might enjoy checking out your comments (and if you want to be devilish, those of your colleagues...).
