Everything on the fediverse really depends on where you go. That’s kinda the whole point.

It’s definitely not just you but you shouldn’t feel bad about it.

It’s on the internet. Public. Got it. It’s almost as if, and hold on to your hats here, the whole point of posting on something like Mastodon or Lemmy or so is to have a public discourse, as you cannot know who will be replying anyways. It’s almost as if, and this is getting wild, I know, read-access being public is intentional and explicitly part of the design.

This is true for Mastodon and Lemmy and I generally agree with this sentiment.

That said, ActivityPub is more than just Lemmy and Mastodon. ActivityPub is more general than that. Lemmy and Mastodon are designed in a way where public discourse is the default and everything you write is expected to be public. But ActivityPub on its own has no such assumptions. There’s nothing about ActivityPub that says that you cannot build a more private social media with it. But actually you can’t really, because of the problems that the blog post points out. But the vision I think for some people is that this should be possible.

I’m personally not 100% convinced that that vision is even possible though tbh.

I love me some calzone with spaghetti bolognese inside of it. It’s very indulgent but so good.

Sure. But lemmy would still not show Mastodon posts outside communities even if they supported that extension. Both parties need to move towards each other.

ActivityPub is an extensible protocol. It is not just one thing. Lemmy only supports posts that follow that extension I linked above. That extension has a definition and Lemmy follows it so in that way it is “standard”. But it is an extension, not part of the core protocol.

Mastodon and most other fediverse services do not support this extension.

Its not that anyone is “doing it wrong” and Mastodon doesn’t really support Lemmys communities either. So Lemmy works in a bit of a funky way that doesn’t match most other fediverse services.

Its just a bit strange that Lemmy does not support the more common posts outside communities since that is how most of the fediverse works, so we’re kinda missing out on a lot of content that we can’t see on Lemmy.

This is the FEP Lemmy uses but most other fediverse services do not use it and Lemmy does not support anything that doesn’t use this FEP. So again, it’s not that Lemmy is doing something wrong, but Lemmy is not supporting how most of the rest of the fediverse functions.

I think Mastodon is very far from standard

I think it’s much closer to standard than Lemmy and I’ve looked into it quite a bit recently. ActivityPub is unfortunately quite focused on microblogging. Honestly lemmys way of doing it is a little hacky.

As for the posts outside communities? That makes sense lemmy-wise I think. Where would those posts be?

I actually think it’s quite straightforward, they’d just be on a users page. This is actually how Reddit has also done it ever since they introduced the feature (much before they enshittified everything else).

You can think of it like every users profile being a community of its own but only the user itself can post to it. Just conceptually speaking.

That would also let you follow users just as you can follow communities.

I mean you could equally ask why does Lemmy not support posts outside communities? It’s on both parties to interoperate I think. Lemmy also uses a specific extension to ActivityPub while Discourse’s posts and Mastodon’s posts and such are pretty standard, but still not picked up by Lemmy.

It has ActivityPub support so it is connected to the fediverse in some ways. Lemmy doesn’t work with it though AFAIK because Lemmy doesn’t support posts made outside communities.
