There's no way I would be able to form a reasonable opinion about an online course given 5 minutes. I had no intention of "belittling" anyone's efforts. A large part of my purpose in posting was to spark a discussion and possibly find out if those efforts have improved. From what people have said, it sounds like they have. So it was by no means a waste of my time to post my comment.

I don't know why you decided to be a jerk about it.
