stu.dicio.us is a great idea and would’ve helped me a lot in college… but what are the chances fellow students who take the same classes would use this service? I entered my university and there were only NINE notes from classes I never took. I also entered the university I attended as a freshman and that had one note. It’s going to take time to build this up besides with students changing (graduating plus entering freshman), it won’t be easy to inform the new students about the service.
