This is what the thread looks like on Wafrn’s side: https://app.wafrn.net/fediverse/post/39562254-048e-4224-8445-36bba052ea91

1. From what I can tell, there have been successful tests with posting to the Threadiverse. I’m not sure how good this experience actually is on Wafrn yet, but it’s promising: https://community.nodebb.org/topic/5fa12345-e4ff-4da3-8a95-d1ef1c4bd186/wafrn-a-tumblr-clone-that-federates-with-fedi-and-now-also-has-opt-in-native-bluesky/
2. I don’t think it will natively support RSS anytime soon. It’s not a bad idea, but I’ve only seen platforms from the Friendica family tree and maybe Emissary supporting this. That being said, a lot of publications are on the Fediverse or Bluesky, and it’s not too complicated to set up an RSS bot?

Oh, I misunderstood, I didn’t realize this related to Tumblr specifically…

Still, it might make some of the dev work easier, if they do end up migrating the backend over to WordPress.

That might be more related to what they’re doing with the WordPress-ActivityPub integration, as a way to work around some of the weird limitations WordPress has for representing notifications and activities other than comments. It’s fairly standard for Fediverse stuff.
