CU Boulder has a rate your prof system in place as part of the University. They call them FCQs (don't ask me what that stands for), but you can go look at a prof's "grades" online and get an idea (actually they build the overall grade into the online course catalogue so when you're looking up and registering for classes you can know). Plus, FCQs are a large basis for receiving tenure at the University, and on one occasion actually got one tenured professor fired! So they DO actually care about them.
Blood and Guts, nuts and blots, yea it's all good!
