You can very easily find the podcast and listen in your podcast player, but I chose YouTube as the link since it is universal and has a preview.

I don't know of a way to link to podcast episodes in a "neutral" way. There is pod(dot)link, but that is far from perfect either (and doesn't have previews).

Yeah don't know a clean way to share them either. Maybe we need a podcast sharing NIP like the torrent NIP...
