I wish there would be end-to-end encrypted, federated micro-blog social media. Social media entries and media aren't stored in plain text, but rather encrypted on the server, and only users who have subscribed to them have the ability to decrypt it.

Ohh, okay - thanks for letting me know. So nothing above 300 characters is visible, unless the Bluesky user opens the post on the original instance.

I suppose this will happen on Bluesky also for long posts from a Facebook-like or Tumblr-like ATProto application? (I don't know for sure, but I think there are no Facebook-like or Tumblr-like ATProto applications at present.)

postscript: I wonder why the last letter "s" from "dialecticalmusings" is cut off on Bluesky?

When I compose a post (woot), WAFRN shows the character count out of 300 character limit of Bluesky (I have enabled Bluesky federation). What happens for posts longer than 300 characters? Do they not federate with Bluesky?

Or is it that everything in the post above 300 characters is not visible to Bluesky users?

Mastodon, for example, also has a 500 character limit, but posts longer than 500 characters from WAFRN or GoToSocial do federate with Mastodon, and can be seen entirely on Mastodon with the "Read more" option. Does this not happen with Bluesky?

If someone writes a Facebook-like or Tumblr-like application on ATProto, would longer-than-300-character-posts from those applications not federate with Bluesky? Or not be entirely visible from Bluesky?

Dave Winer, @davew is basically the inventor of RSS and I take the chance to mention him as I am doing my best to be an RSS advocate with my own possibilities and limits, even with non-technical people who don't understand why I insist in "so complex things" when "commercial platforms give you everything in an instant".
I talked about ActivityPub and RSS during my last WordCamp, Pisa -Italy- 22nd November 2025. Italian, unfortunately; I'll share my talk when it's out on WordPress TV but I fear there won't be English subtitles.

But I limited what I wanted to say because a word could violate WordPress's code of conduct.
It's nothing obscene, it's the metaphoric name of an anchor-stone. But in Venice they call it "coion", like the vulgar word for testicle. It's basically a round stone structure which firmly anchors the arch of a bridge, to its vertical support. It's invisible to human eyes, people even don't know it exists. But it allows Venetian bridges to resist for centuries. It's fundamental. But if for a reason or another it becomes visible, it means that the bridge is damaged.
Same way of a linchpin for a wheel.

This word is even used for a person. When someone is essential for a community, determines its success too, but if they get attention or ask for visibility, they could even become an obstacle. Or they are treated as such. No idea if the word corresponding to "coion" for a person has the same idea in English. I have found "moron" but I don't know if it's the same.
Basically, when you are important and have not a very strong personality, so you let others treat you as invisible, they consider you as always available, always granted. And treat you badly if you raise your hand and say "I'm here too"; they immediately send you back to your place.

RSS is treated the same: many of commercial platform users don't even know about its existence but without RSS, no newspaper or whatever social pages sharing news automatically, could fetch contents.
I agree with Dave when he says that RSS is more important than ActivityPub. Simply RSS can work without ActivityPub but often not vice-versa.

You comment on your own posts because you’re a loser. I comment on my own posts because I’m testing building an ActivityPub compatible social media platform.

[Fediverse BackUp]

So, I think an (ActivityPub / ActivityStreams) Activity File COULD be a "good" format for backing-up a single post on the Fediverse, but —

Most (maybe all) extant Fediverse software would need to change a bit. Fediverse software would need to support embedding "everything" in a single Activity File (rather than referring to "everything" else by URLs).

Also — what about comments / replies —

Someone people (including me) would want at least some of the comments / replies to be included in a BackUp for a post.

So, for an Activity File to be a "good" format for a BackUp, a single Activity File would also need to contain (all or selected) the comments / replies to the post.

Also — we would need to consider Threads / Storms —

Where people reply to their own post to make a larger post made up of smaller posts.

(I.e., what I have been doing here 🙂 )

But — for an Activity File to be a "good" format for a BackUp, there would need to be a way to get the Fediverse software to embed the (non-text) media (such as images, audio, video, etc) into an Activity File.

[Fediverse BackUp]

Now, having said that, I don't think there is anything about ActivityPub / ActivityStreams that "prevents" Fediverse software from not embedding (non-text) media (such as images, audio, video, etc) into an Activity File —

For example, an "Image" Object can contain a ("mediaType" and a) "content" field (rather than an "href" field).
