The idea is cool with all the apps interconnecting, but where do I go to actually see this in practice. Does the cross communication only work on platforms like Mbin/piefed, or am I not seeing something.
I keep hearing thanks to activity pub posts here can be seen and replied to from elsewhere, but I haven’t seen it.
Yes, I know :) (I run a family instance with FediFetcher and relays as well)
Large instances are usually well covered enough. I don’t know if Lemmy/Mbin pull sll posts for a thread you visit but Mastodon has plans to do so in the future to alleviate this issue.
