Just put it anywhere publicly on the internet. Preferably NOT a google doc because that isn’t very discoverable. More like on your own blog / substack.
If you prefer a more private space I recommend having a “personal notebook” via Obsidian / GitHub. This way you can have all your notes be public but it doesn’t have to be super polished / it’s an evolving thing.
See my guide Host your Obsidian notebook on GitHub Pages for free
An example of this is my own notebook: https://defenderofbasic.github.io/notebook/. I have also started using the GitHub repo to maintain a public “review queue” so people can send me things to review and my write up is public: https://github.com/DefenderOfBasic/notebook/issues
The reading guide is meant to be a “suggested starting place”. If you’re not sure where to start, pick one of them and answer it. If you’ve read it and already have a lot of thoughts/strong opinions, just go with that! Let your curiosity lead you.
