Every professor or teacher I have spoken with loves the idea of them being able to help and reach more individuals now with platforms like Coursera, Khan Academy, and SchoolKeep. My guess is a lot of them do it because they love teaching. However, for some it may help them get recognition and grants too for their research or school. I wouldn't doubt if some are being asked to speak at conferences and getting paid that way because of their reach & influence through MOOCs platforms either.
