Coursera is awesome. I'm 4 weeks into an introductory finance class and professor Kaul is doing such a good job of introducing concepts to us (I have no finance background).
I second that. I am following the same course and while I have some prior finance training this is nevertheless very useful to better understand some stuff I simply applied before. Great, great stuff.
Yes the Finance class is going well for me too. I tried taking the SaaS class but I didn't like it.
The Finance professor is just right, I can watch the videos on 1.75x speed, and I'm finally getting the hang of the confusing, unintuitive and restrictive Coursera UI.
Udacity has some challenges as UReddit too. I took a "software testing" class recently, and you can tell the instructor ended the course earlier than planned.
A 6 week class was effectively only a 3-4 week class. The first two weeks had embedded quizzes, and homework. By the end, it was watch this short video and no homework.
