College students use the frank Rate My Professors to help them choose their classes. Leslie Fields, Monitor at Crowell Public Library says, “This site was *so* helpful to me when I was in school. It helped me to avoid bad teachers, or to see if they taught one class better than others.” (Apparently, some professors are more effective when instructing small upper level seminars than they at inspiring a large survey class.) “I used this all the time!” she declares. These days, Fields could rate her instructors via cell phone with the free iPhone app [http://itunes.apple.com/us/app/rate-my-professors/id345381821].
