I rarely see any SAAS here related to e-learning e.g. courses. Is there any particular reason for that? I thought about creating courses on udemy, but the constant sales and overall quality of a majority of the courses don’t really attract me. Creating your own site and having a subscription option seems like a viable strategy (e.g. I’m subscribed to openstudiojazz.com). You could provide something unique in terms of the learning experience instead of just putting up a bunch of videos.
