We previously blogged (here, here, and here) the dangers to faculty posed by RateMyProfessors.com, which now boasts over 5.75 million student evaluations of faculty.  Inside Higher Ed has an interesting article on the dangers YouTube poses for faculty:  You May Have Been YouTubed, by Scott Jaschik:

If you don’t like what RateMyProfessors.com has done for the image of professors, get ready for the YouTube effect. YouTube is the immensely popular Web site where people post videos of themselves and their friends hanging out, doing mock television shows, watching television, or just about anything you can imagine in front of a video camera of some sort.

The blog Metaspencer predicted that YouTube would have an impact that builds on the way RateMyProfessors.com has intimidated many faculty members — who hate the site and check to see how they are doing on it. “When that site first went online, many seemed outraged that college level instructors would be publicly assessed in this way, outside of our already established course-evaluation-systems, and in many cases, professors have been graphically slandered and bodily objectified on that site. RateMyProfessors.com made our lives as college level instructors suddenly unstable and encouraged some of us to be just a bit more careful, if that’s the right word, when it comes to what we do in the classroom,” the blog said. “Videos of teachers on YouTube, however, magnify whatever paranoia RateMyProfessors.com may have generated. Were you videotaped in front of your class yesterday? Today? Yesterday? Will what you do with your students be edited and presented in a way that you feel misrepresents how you teach?”

In my unscientific survey of YouTube, I found 2550 videos indexed under "professor," but only four indexed under "law professor."
