i could make arguments that nostr does fix a lot of the decentralization issues with podcasting, but that only happens if we don't all centralize around the same blossom media servers or nostr music and podcast platforms. baby steps. rss isn't going aways anytime soon. it's been around for 2.5 decades. it's best to build tools that utilize both rss and nostr for the time being because no one knows what the future holds.
