I recently migrated or better yet am still in the process of migrating from feddit.de to dataterm.digital. I really like it here and probably will stay here but I’ve been wondering about the difference in the “all” feed when comparing the 2 instances. On feddit.de’s “all” feed I see many more new posts than on dataterm.digital’s “all” feed. (I’m comparing sorted by new)
Can someone explain to me why that is and what’s happening there? Shouldn’t I be seeing the same posts regardless of the instances, given the instance isn’t defederated?
The fediverse is deliberately designed not to do that as federation is not cheap in terms of computing resources. I believe it’s exponentially complex as the number of federated instances grows, at least that’s my understanding with Mastodon.
There exist ActivityPub relays that are basically already filled indexes that you can connect to a Mastodon instance. This is what it says in the admin settings:
