I've completed one course (why I bothered I don't know) and I've subscribed to and watched all the videos of a couple courses, and they have an absolute fixation on video even when its completely unnecessary, the videos tend to be very short, and have constant quiz interruptions. So its not going to fly as something you consume while doing something else, like driving or riding a bike or yardwork or shoveling snow or hiking or whatever. Have to stop what you're doing and fumble with the phone for half a minute, every five minutes.
If someone would rip the videos off Coursera, strip out the unneeded video, concatenate, and upload to archive.org it could work out pretty well.
Could you be more specific? Is there anything you've watched that is worth viewing? Not all free courses are out there are equal. Sometimes the audio is distorted, and the presenter isn't so good at relaying material or enthusiasm for the material.
My experience with Coursera is that the technical quality is consistent and of suitable quality. In addition faculty is often fully engaged in the discussion forums. In some cases the lead instructor "wrote the book" on the subject and is actively answering questions, e.g. Ullman in Automata.
However, the presentations vary in terms of pure entertainment. This hasn't mattered to me because I select courses by content. Cat videos I can get anywhere.
