@James Cridland @npub1rcnr...dw4h or any other #Podcasting20 colleague.
Do you know the project LibriVox [1] ? It's "Free public domain audiobooks" with RSS capabilities.
There are some audiobooks already on the PI [2], but not all. And some via iono.fm feed instead of librivox.org/rss/.
This could be a good place to improve the medium tag adoption (CC @npub1thg9...zq23 )
I've not found the infrastructure open sourced to do some PR, but they are Public Domain.
So I think we should contact [3] them to help them adopt P20 tags on their feeds.
