Provide a standard (client-neutral) podcast feed
The podcast page https://80000hours.org/podcast/ provides links to listen through spotify, apple, etcetera, but it lacks a standard, vendor-neutral feed. Pretty much every other podcast has an RSS/Atom-based feed, so people can use any client they like.
Depending on how you currently create your podcast, such a feed might already be generated, but simply not linked to on the website?
Note the website does have an RSS feed, but it appears to only present the episodes as blog posts, so podcast apps (e.g. AntennaPod) do not know how to obtain the audio files.
