Hi Ron,

Thanks for reaching out. Yes, that's an interesting idea you bring up, but I'm not quite sure where the non-subscribed version stops, so you may have missed some of the main concepts. One of the point is that concept maps are created by hand, but it's a bit complex to elaborate in a reply to your comment. :-) However, I can strongly recommend a medium subscription. It is my primary source of inspiration and goto place for descriptions of practically any subject. Please use my referral link if you decide to join the club :-) It won't cost you extra. https://medium.com/membership/@rkursem
