Thanks for the ideas. Exactly, something like running commentary / different approaches could work. I greatly prefer text to online videos [not sure why, I think I get impatient that I can't read at the exact speed I want?] and would go through those.

Wikipedia is self-described as a reference [not teaching tool], stackexchange is good for point-fixes [q&a], but some more "guided tour" could be useful. Especially to help appreciate math as an art/journey vs. pure problem solving.
