@jeremy @pluralistic calling #ATproto aka. #BlueSky "federated" is as much as a #lie as calling #Discord instances as "#Servers"...
- Unlike #ActivityPub there's no cleanroom & fully self-hosting capable implementation!

Função muito supimpa do #SNAC que só recentemente constatei como é útil: podemos pôr no texto a ligação para uma imagem externa, que ele a transforma em anexo da "atividade" (a publicação no #ActivityPub), sem precisar armazená-la! Pode notar que essa foto do Locutus — Cap. Picard (Patrick Stewart) assimilado pelos Borg — é descarregada diretamente da Wikimedia Commons! 
Não sei se outros sistemas, mesmo os que também já suportam #Markdown, fazem isso! Quem aí pode dizer?

Thinking of spinning up a WriteFreely instance on a VPS I have sitting around. Anyone using it at all for personal blogging or even other writing endeavors?

Now you've elaborated, I do seem to remember quite a few people posting about #peertube - and #lemmy to a lesser extent.
I think there may be special issues with the way they use #ActivityPub but I hasten to add, I don't know the ins an outs of it well enough to say for sure.
It's interesting that #friendica works more or less perfectly though, despite being at least as complex as the others you mention.
I wonder if it's because it's far older, so everyone already knows how to allow for its quirks.
It's an interesting topic though - and obviously one I follow :)

I'm moving posts regarding my #activitypub projects to Tokler. I want to post travel photos and my dogs on Postygram. So here is where Raels and Tynkle development posts will go. #tiktok #fediverse

the best way I saw #ActivityPub explained was as being like email protocols.
On the most basic level, text works, but the more complexity you add the more inconsistency you see.
For example, if you attach large files, some email providers will not deliver it. If you use some css some email services won't format it the same way.
And recently - well about a year ago - some yahoo accounts weren't able to receive some exchange emails.
We're all so used to this we don't even think about, but from what I've read it;'s the same issue at work with the #fediverse.
Because servers get so much freedom in how to operate, it breaks things for some users.
The social media we're used to is more homogeneous, but it wasn't always that way.
We used to have these issues with #nntp servers, where for example some servers refused to encapsulate #yenc messages correctly
It's not that #mastodon is the new way; it's just that we've forgotten the old way :)

Dumb question that I was always too afraid to ask:
I know how the #Fediverse and its federation works. It's intuitive and familiar to me; I mean, I even host my own instance.
But I never understood how interaction cross-software is supposed to work. In theory, I can use whatever #ActivityPub software I want and still interact with everyone else. But in practice that just... isn't the case, right?
I mean, for text it's quite simple: I write a short post on #Mastodon and people on #GoToSocial or #Misskey or whatever can see and read that same post and interact with it. They can see my profile and it appears on their instance in their style and with their features.
Even outside of microblogging I still get it. A super-long post on #Friendica or #Diaspora appears on my timeline, too. Their profiles might have more fields than I can see here, but that's fine.
But what's up beyond that?
I can see #Pixelfed posts here, converted into image galleries. But what about the other way 'round? If someone on Pixelfed follows my Mastodon account, they can't see any of my non-image posts, right?
What about #PeerTube and such niche software? I guess I could follow a PeerTube account as a microblogger and see their videos and descriptions in my timeline. Video comments are replies.
But the other way 'round? How are they supposed to interact with Friendica or Pixelfed users? PeerTube doesn't even have a "timeline".
Doesn't that feature disparity undermine the whole idea of the #Fediverse or am I missing something?

Is anyone aware of a FEP for that?

I just realized that the default specifications for ActivityPub/ActivityStreams do not have a way to perform an update on an object's ID. (ie, moving it from example.com/1 -> example.com/2)
An Update activity does not allow ID updates because it would lose the reference to the original one. (It can be massaged by using an Origin property, but I don't like that).
Another option would be to use a Move activity (which is defined as moving objects between collections), where the Origin property is the object itself instead of a collection. (I like this behaviour better, as it requires less divergence from the spec)
