I think fountain is great as a nostr first podcasting 2.0 app. It's a novel feature to see the discussion about the podcast in the app. But I get if that's not wanted or liked.

However, as a podcast app, it is not better IMHO as even non PC2.0 apps.

For example, pocket casts would pause the audio when navigation came on, fountain doesn't seem to.

But that's fine, all technology has tradeoffs. In general, most technophiles never tell you what something doesn't do.
