Some really nice suggestions in the article that for whatever reason are not often brought up while discussing maths education.

A good way to bootstrap the "math avengers" website would be to get people to write up running commentary to some classic maths texts, e.g. Silvanus Thompson (out of copyright), Halmos, Rudin etc.

Essentially all high school maths programs are less than great to put it politely and often created by people with rather limited appreciation of the subject. Better university textbooks are not readily accessible without an instructor. Running commentary from several authors giveing additional motivation, examples, clarifications or alternative derivations can be of great help to students and wikipedia style platform can be great for organising such a project.

Sites like wikipedia and mathoverflow / stackexchange are great for specific questions but lack structure - centering the efforts around certain "canonical" texts can help to organise the material which otherwise would be overwhelming.

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.
