Kudos for being a <not-for-profit>. Also, anyone can create content: <e-learning websites must allow students to create learning content>. Oh, but TODO is possible for anyone to make content publicly visible? Course join links lik: https://www.khanacademy.org/join/MJZ6NSV7 require login. https://webapps.stackexchange.com/questions/165132/how-to-create-a-course-that-is-publicly-visible-without-the-need-to-login-on-kha If that's the case, it is a fatal flaw not shared by <OurBigBook.com>.
Another cool aspect is that they have the "physical world teacher pull student accounts in" approach built-in quite well at course creation. This is a very good feature.
As of 2021 they were a bit struggling for money it seems: https://www.youtube.com/watch?v=I8XdUy-wyyM[]?
