I think it is a useful service, because it helps small instances discover content. However, this idea is not new and another service of that kind, FediBuzz, has been operating for a long time.

@robert.meyer86 See also https://codeberg.org/fediverse/fep/src/branch/main/fep/ef61/fep-ef61.md. This is already part of Fediverse and has multiple implementations.


@SorteKanin My server translates Lemmy upvotes into likes and downvotes into dislikes. That blends quite well in the UI with Mastodon’s “favorites” and Pleroma/Misskey emoji reactions, so I think Lemmy’s assumptions are correct


Identity based on a pubic key is already not theoretical, it is supported by services that implement FEP-ef61.
I am not sure whether it makes sense to separate data hosting and feed generation, this will probably require a specific network architecture, similar to Bluesky, which tends to be centralized.


I doubt that it will be implemented in Lemmy, the application architecture needs to be different in order to support cryptographic identities.
But there are other implementations (they are listed near the end of the document).


That’s correct.
did: prefix is used to denote cryptographic identifiers, in theory one could even take a did:plc identifier from Bluesky and then use it as identity for an ActivityPub application:


Yes, domain names can be replaced with cryptographic identifiers: https://codeberg.org/fediverse/fep/src/branch/main/fep/ef61/fep-ef61.md
If you run a small micro-blog instance, you follow some people and maybe some communities. Tagged posts come only through these follows, so you only see a tiny portion of all tagged posts.
A hashtag relay tries to aggregate tagged posts from the whole network. By following a hashtag on such relay you can see more posts on the topic that interests you.
