I check Rate My Professors for every registration. It's very reliable once you learn to read between the lines of some reviews. One professor is particular is really great, and I'd sign up for a class with him each semester even if the topic isn't interesting to me. He even suggested pursuing publication for a term paper I wrote, and helped me through the process. It takes a special kind of person to be able to do that, and it seems like those types of professors are the kind of people who are happy spending all day working on academic stuff. The previously mentioned professor goes home in the evenings and devours books and news to catch up with the latest developments in his field. Another professor sits in his office until 7-8 in the evening. They live in breathe their studies but I try not to fault those who want to have a life outside of academia too.
