Myspace professor ratings
I noticed myspace has added a really cool feature which allows you to grade professors in college that you have had. This can serve as a guide for students signing up for classes to make sure they get decent teachers.
I also see this being a really good tool for teachers to use to get honest feedback on their performance. It will encourage teachers to improve their teaching if they become less popular because they are rated poorly.
There were already quite a few ratings for teachers at UVSC and I was able to add my own. The more people who use it, the more useful it will be.
