A MOOC I'm currently taking, and possibly soon dropping, is heavy on functional programming (with a language whose syntax has been pretty new to me), primarily through 1.5 hour lectures. The professor is quite skilled, but the convenience of that video format is often overshadowed by both needing to wait for lectures to be published and having to pay complete attention to them for 90 minutes a pop.
In contrast, lectures accompanied by well-produced written material allow me to skip areas I have a grasp on, or provide a resource to reference much more quickly when I need to review a topic. Having to guess which lecture, and where in that lecture, a comment occurred is a significant spend of time.
