- podcast episodes are not nostr events no - the reason being is that we want the social aspect of nostr to apply to all podcasts without podcasters having to make a conscious choice to use nostr

- podcasts are referenced in events using NIP-73 External Content IDs i + k tags, the k tag represents the external content id kind so you can query all the events for that kind from any relay (all events referencing podcasts), and the i tag has the podcast show / episode guid value so you can query all events for a specific show / episode - the guids are an rss podcast spec unique id that is maintained even if you switch hosting companies

- boosts work using a quoted zap event - the zap receipt (kind 9735) is embedded in the kind1 note in the same way quoted notes are - with the nostr:nevent1... encoding

- also for comments we plan to switch from kind 1 to kind 1111 - should have this done soon
