Th is new enterprise is the logical extension of an idea that goes back decades to when I was in college. Back then, friends would take notes for late sleepers or lazy classmates. The practice then escalated so that friends would alternate to take notes for each other's classes. Today, students are being hired to take notes mostly in core courses. This practice has seen its share of critics.
Some professors feel it's a form of cheating the educational process.
The student, in effect, is not totally involved with the material or course. These professors who criticize online notes really need to get out more often. Term papers, CliffsNotes, and synopses of the classics have been available for years. They were never meant to act as a substitute for education. Rather, their purpose has always been to supplement class notes, assigned reading, and whatever interaction can be gleaned from the professor.
