@Moon If you have other suggestions to look into I'd definitely check them out.
Overall the goals are to have shownotes that can federate and generate emails for when we go live weekly. Ideally, since we archive and self host a lot of the articles that we pull, we'd be able to start building out a curated shownotes database using something like https://logseq.com/ or https://docs.freeplane.org/
Then when we publish the mp3, our chapter json shownotes link would point to the headers.
