I believe a quality online course is one that truly transforms students in a positive way. They are challenged but not burdened. They leave the course with a new knowledge, skills, abilities and attitudes that they either didn't have beforehand or that needed to be strengthened and renewed. An online teacher facilitates this learning journey. Content coverage alone can't do it. Just passing the course won't do it either. It takes true engagement, interaction and little bit of productive struggle to make it worthwhile.
