The biggest issue I've seen in online courses is production values. In fact I think crap production values and the lack of a quality bar is why platforms like Coursera have done poorly compared to their potential.

The most obvious issue is usually microphone quality. It's baffling that people spend so much effort developing a course and multiply that effort by a shit microphone. If you aren't willing to spend/get money for a good microphone, your philosophy on what is important for online teaching may have some blind spots IMO.
