I do not know if the forum has the structure needed for something like that. There are thousands of other structures much better prepared.
But I believe that the forum could be used to debate more ideas and concepts between people who do not totally dominate a subject. That is, they could have specific sections, with suggestions of supporting materials and guides where the average user could discuss the subject and study more about. Maybe with designated tutors. Experts on a given subject, helping and moderating.
I, for example, do not understand practically anything about most of the new protocols or about second layer solutions in Bitcoin. Having a section targeted with a roadmap and many reading suggestions plus a dedicated space for discussions could be interesting.
And as it is a brainstorming, I leave as a suggestion that courses on economics could be very interesting as well. Especially about game theory. One of the most spectacular courses on this subject and that is free can be found here:
