Sharing Content on the Internet
Content on the internet is easy to share with a link - just copy the url and you’re good to go.
But links are limited in their ability to quickly transfer information from person to person. Open Graph metadata can only convey so much, and people receiving the link need to firstly decide whether to click it, and then secondly decide whether to read / watch / listen to whatever content is behind the link.
Modern social media platforms have better sharing mechanics. Quotes on X, highlights on Substack, and clips On YouTube make it easier for people receiving a share to digest what they are seeing and decide whether they should pay attention.
Nostr enables these rich content sharing experiences to exist on the open internet without any single platform controlling their visibility or reach.
Applying Nostr Highlights to Podcasts
Podcasts are already an open format where you can listen in any app - but sharing episodes is still constrained to basic links tied to a single platform.
We can do better!
The podcast:transcript tag allows podcasters to include transcripts for episodes in their RSS feed, and has wide adoption from hosting companies meaning that most episodes now have transcripts available.
NIP-73 External Content IDs allows any nostr event to canonically reference a podcast episode by including the <podcast:guid> reference ids as queryable i tags.
NIP-84 Highlights signal content people find valuable in a contextual way that links back to the original content.
Combining these 3 primitives allows anyone to share a highlight from a podcast episode that is easily digestible, accessible on any app, and canonically references the podcast episode.
Highlights in the Fountain App
Here’s what these nostr podcast highlights look like in Fountain:
To create a highlight you simply:
- tap on the episode transcript from the player
- select the part of the transcript you want to share
- post on nostr with an optional comment
Fountain inserts a timestamped episode link into the highlight r tag - so people viewing the highlight on other nostr clients can tap through and listen from the position of the highlight.
Your highlights are nostr native - so they can be liked, zapped, reposted, quoted, or replied to on supporting clients like Damus and Amethyst. Primal are working on supporting highlights in their feeds as well.
Other podcast apps can query these highlights and render native episode cards based on the <podcast:guid> tags and their own internal database.
