Connecting the "Wherever You Get Your Podcasts" blog I posted a ~month ago (https://knotbin.leaflet.pub/3lx3uqveyj22f) to interoperability in atproto.m using the podcast metaphor for feature adoption & how they're just one type of RSS feed, just like lexicons with records. In theory, apps can implement any lexicon. I'd then go into the actual experience of implementing this at the huge scale of Bluesky's lexicon and why Spark decided to take a different approach to lexicon interop in the end.
