I find the inclusion of every federated instance in ‘All’ fairly annoying. New tiny/niche/vanity instances get added by default when federated. There ends up being too much duplication and stuff I’m not interested in.
I’d much rather a system that only includes the local instance by default with a way to discover and add other instances.
My instance block list is long but there’s always new instances to block. For me, this a design flaw of the fediverse.


so you want to be able to subscribe to instances and have a new feed for the “Subscribed Instances” (as opposed to the existing Subscribed for communities)
not directly related, but have you looked at Feeds and Topics? https://piefed.social/feeds and https://piefed.social/topics
You can also follow remote feeds https://piefed.social/feed/add_remote
No, I didn’t know about those. Thanks, I’ll check that out.
All those things are on the ‘Explore’ menu.
You can also create your own feeds
