Both adding Nostr support to a feed reader, as well as adding RSS/Atom support to a Nostr reader (that is optimized for long-form content) would be nice to have. It's basically the same app and the protocol shouldn't even matter much to a user. Ideally the experience is exactly the same when you paste a Nostr URI as when you paste a RSS or Atom URL.

I rely heavily on Feedbin for most of my news and long-form content, so for now I'll just subscribe to Nostr feeds using my own Nostr feed generator. There's hardly any long-form content on Nostr as of now, so opening e.g. Habla a few times a day, with zero updates for most of the week, was too frustrating of an experience.
