This is a great idea! We are trying to do the same at a more basic level, publishing on STEEMIT some of the free lessons available on our website. Our mission is to spread our knowledge among people interested in IT, Cryptography and Maths.

@sndbox From our point of view, it could be interesting to add a "CHANNEL FEATURE" to STEEMIT. So, if someone is organizing different online courses or writes on different topics, he could split the posts in dedicated channels and users could decide to follow just one channel or the other.
