This image from the Chandra X-ray Observatory, the world's most powerful X-ray telescope, shows the Cygnus Loop, also known as the Veil Nebula, a supernova remnant of the explosive death of a massive star. This 3D model is the result of a simulation showing the interaction of a blast wave from the explosion with an isolated cloud of the interstellar medium, dust and gas in between the stars. via NASA/SAO/CXC

An image from the Webb Telescope shows outflow from a newly forming star, giving this Herbig-Haro object (HH 49/50) its nickname, the “cosmic tornado.” This pillar of gas and dust looks like it’s topped by a galaxy, but in reality the galaxy is light years away. Herbig-Haro objects are outflows produced by jets launched from a nearby, forming star (in this case, out of frame at lower right).

@TeflonTrout :bc: he/him @Sharp Leaves Still, forcing Mastodon's culture and Mastodon's unwritten rules upon literally everyone in the Fediverse is bad.

Maybe you haven't heard about this yet, but: The Fediverse is not only Mastodon. It has never been only Mastodon. It didn't even start with Mastodon. And it doesn't entirely work like Mastodon either.

For starters, this means that just because you see it on Mastodon, it didn't necessarily originate on Mastodon.

There are places in the Fediverse that are vastly older than Mastodon, and that are very different from Mastodon. Thus, they have their own culture, based on their own technology and their own features and where their users came from, and largely without any influences from Mastodon.

The oldest still existing server software in the Fediverse is not Mastodon from 2016. It's Friendica (https://friendi.ca, https://en.wikipedia.org/wiki/Friendica, https://joinfediverse.wiki/Friendica). Friendica is essentially a mixture of a Facebook alternative and fully-featured long-form blogging. No Twitter or Mastodon influence anywhere. And Friendica first came out in May, 2010, five years and eight months before Mastodon.

Friendica did not intrude into the Mastodon Fediverse that was created by Eugen Rochko as a Mastodon-only network. Mastodon was born into an already existing Fediverse that consisted of at least Friendica, Hubzilla (https://hubzilla.org, https://en.wikipedia.org/wiki/Hubzilla, https://joinfediverse.wiki/Hubzilla) and GNU social (https://en.wikipedia.org/wiki/GNU_social; now defunct).

Here's how Friendica differs from Mastodon in ways that may disturb Mastodon hardliners:
  • Mastodon is hard-coded to 500 characters. This character limit is deeply engrained into Mastodon's culture.
    Friendica doesn't have an arbitrary character limit; it's limited by the maximum size of the database field for the post text. Currently, this is 16,777,215 characters. Thus, Friendica doesn't have keeping messages short in its culture, it never has, and it never will.
  • Mastodon users tend to be eager to block anyone who doesn't cut long posts into pieces of no more than 500 characters each.
    I know at least one Friendica veteran who blocks everyone upon first strike who does cut long posts into annoying strings of tiny chunks.
  • Mastodon introduced a CW field in 2017.
    Friendica has had the exact same field as a summary/abstract field since its own beginning in 2010. That, and Friendica has always had a much more efficient way of handling CWs, one that Mastodon itself adopted with version 4.0 in October, 2022. Thus, by its technology and culture, Friendica users despise misusing their abstract field to force the same CW upon everyone out there with a hot, flaming passion.
    So if you see someone "misusing" the CW field for "a subject or a summary or whatever that is," that might not be a clueless Mastodon user. Instead, it might be a Friendica user who has been around for a dozen years longer than you, who is used to living by Friendica's culture, and who knows tons more about the Fediverse than you do.
  • Friendica users are much less likely to add alt-texts to their images. That's for two reasons.
    One, Friendica's culture is not an idealised version of pre-Musk, very-left-wing Twitter's culture. It does not include attacking and punishing everyone who doesn't add 100% hand-written, 100% accurate, sufficiently detailed alt-texts to their images.
    Two, Friendica handles images drastically differently from Mastodon. Mastodon always has a nifty little entry field for alt-texts whenever you attach an image. On Friendica, images are embedded into posts rather than attached to them, like in a blog post. And oftentimes, you literally have to program the alt-text into the raw image embedding markup code.
  • On Mastodon, it's considered intrusive and reply-guying to reply to someone who hasn't mentioned you, and to whom you aren't mutually connected. You couldn't possibly have received the toot that you're replying to otherwise.
    On Friendica, that's perfectly normal. Friendica doesn't show you single messages by default. It always shows you the entire conversation thread, all the way up to the start post, with all branches. Thus, neither Friendica's technology nor Friendica's culture rules out replying to any comment in the thread.
  • Mastodon has only just introduced Twitter-style quote-posts a few months ago. With a safety feature that only works on Mastodon and GoToSocial for fear of that feature being used for harassment and dogpiling just like on Twitter. And because literally everyone on Mastodon comes from Twitter, it's actually being used for harassment and dogpiling.
    Friendica has had that very same feature since its inception in 2010, over a decade and a half longer. It has never not had this feature. It has always been able to quote-post any public message in the Fediverse. But since Friendica is not entirely populated by former Twitter users, it hasn't been used for harassment or dogpiling even once. It's only used to forward content. For most of the time, it literally was the only available way to forward a message.
  • Mastodon users tend to be very protective and defensive about their allegedly Mastodon-only Fediverse.
    Friendica users are used to being able to connect with everything that moves and then some. It's one of Friendica's key features that it speaks a whole lot of protocols, not just ActivityPub.
    Whereas Mastodon users see Mastodon as a "decentralised walled garden", Friendica users see Friendica as the gateway to the whole federated social Web plus some places that aren't, strictly speaking, federated.
  • Mastodon users will staunchly insist that "Fediverse" and "Mastodon" essentially mean the same because they believe they do. They will attack anyone who claims otherwise.
    Friendica users will staunchly insist that there's a huge difference between "Fediverse" and "Mastodon" because they actually know there is one. They will lecture anyone who claims otherwise.

Of course, from a Mastodon point of view, it's both tempting and fully justified to tell the Friendica users that this is the Mastodon Fediverse, and that they will have to adapt the Mastodon culture and abolish their own culture or be thrown out. But for one, Mastodon's culture doesn't fit Friendica's technology.

Besides, that'd literally be like European settlers holding Native Americans at gunpoint and forcing them to give up their own culture, adopt European culture and convert to Catholic Christianity or else. The only difference is that European settlers, unlike the Mastodon users, did not think that they were there first, and that everyone else is an intruder.

I mean, sure, go ahead and attack anyone who doesn't strictly live by Mastodon's culture and Mastodon's rules if you think you have to. But prepare for a whole lot of defence and even counter-attacks from Pleroma, Akkoma, Misskey, Iceshrimp-JS, Iceshrimp.NET, Sharkey, GoToSocial, Hollo, snac2, Mitra, Socialhome, Friendica, Hubzilla, (streams), Forte and the rest of the non-Mastodon Fediverse.

@🌱🏴‍🅰️🏳️‍⚧️🐧🔧📎 Ambiyelp Let me give you an example. Something that I've actually posted myself.

Here's the image (CW: eye contact): https://streams.elsmussols.net/photos/jupiter_rowland/image/ff28c33e-f633-4801-ad2b-c3dcd40d7bf9

Here's the alt-text:
Image macro, based on a screen capture from the Disney and Pixar animated film Finding Nemo. At the top, there is a white space with a two-line caption: “OSgrid: offline for weeks to come,” and “Owners of other grids, looking at OSgrid residents:”. In the screen capture below, ten seagulls are perched on two mooring lines in the background. An eleventh seagull pokes its head into the image from the bottom right. They all look at the camera. Each one is labelled with the question, “Mine?”

Do you understand the image without explanations?

I guarantee you that there are loads of people who don't even understand the template, and that next to nobody out there understands the topic. Not without an explanation.

So here's the explanation in the post text, including a link to the corresponding KnowYourMeme page:

Explanation:


The image macro is based on the "Mine? Mine? Mine? Seagulls" meme template (link CW: eye contact; https://knowyourmeme.com/memes/mine-mine-mine-seagulls).

OSgrid (https://osgrid.org) is a 3-D virtual world, based on OpenSimulator (http://opensimulator.org; https://en.wikipedia.org/wiki/OpenSimulator; https://hub.netzgemeinde.eu/item/ba1b1cb6-7c18-410e-8752-df4b4face2e0), a free, open-source server-side re-implementation of the technology of Second Life (https://www.secondlife.com; https://en.wikipedia.org/wiki/Second_Life). Like Second Life and all other OpenSimulator-based worlds, it is called a "grid" because it is divided into square regions bordering on each other.

Launched in July, 2007, OSgrid was the first public OpenSimulator grid, it is the oldest and one of the biggest by both land area and users. This means that while it's running bleeding-edge developer versions of OpenSimulator, it also carries around a whole lot of old ballast. It is notorious for going offline for maintenance and for this maintenance often lasting for a week or several, and it is just as notorious for going offline with no announcement and either only a very belated explanation by the admins or none at all.

The last prolonged downtime before this one was in 2025. It included OSgrid's entire asset server being wiped clean, and all avatars in OSgrid having their inventories emptied almost completely. It was scheduled, but due to OSgrid's instability at the time, it happened spontaneously and way ahead of schedule. The OSgrid admins could not say for how long OSgrid would be offline, but they estimated the downtime to exceed one month. In addition, for several years before that shutdown, each OSgrid shutdown had led to more and more lost assets already.

This drove many OSgrid residents away from OSgrid and to other OpenSimulator grids. Most of them, OSgrid included, are connected by the so-called Hypergrid which makes it possible for avatars from one grid to teleport to other grids, so it doesn't matter much which grid your avatar is registered on when you want to travel to certain locations or events. Many of those who had left OSgrid when it was offline returned after it went online again because the asset server had been promised to work as intended now.

Still, with OSgrid's track record of unreliability and, most importantly, losing assets, some residents fear that the current downtime might break more than it will fix. Not few think that if they've lost their whole inventories "unannounced" last time, they will lose their whole inventories actually unannounced this time. And so they're looking for a new home again.

Of course, this has the owners and admins of many other grids wishing for as many OSgrid residents as possible to join their grids. The advertising of other grids in the wake of OSgrid's downtime has already begun.

Now, there are people who say that linking to external explanations is ableist crap because that's inconvenient, and because these external websites may not be sufficiently accessible. Oh, and links don't work in alt-text (only that the above link went into the post text where links do work). So if you post something that needs to be explained, explain it yourself.

Sure, but that'll be an explanation of the "Mine? Mine? Mine? Seagulls" meme template. In addition, there will have to be one explanation for Reddit and one for reaction images because people won't understand the template explanation otherwise. On top of that, there will have to be an explanation for image boards, Futaba Channel and 4chan because people won't understand the reaction image explanation otherwise. In fact, I might also have to explain the film Finding Nemo.

For comparison, I've once posted something based on "One Does Not Simply Walk Into Mordor". It was the only time I've explained the whole thing myself. That was one explanation for my image, six for the template, two for the topic (and that was actually Fediverse-related, but still obscure), that's nine altogether. I haven't even explained The Lord of the Rings, the character Boromir and that particular situation. Still, that was 25,000 characters of explanation overall, half of which accounted for the six explanations for the template.

@🌱🏴‍🅰️🏳️‍⚧️🐧🔧📎 Ambiyelp I'm not talking about the visual description in the alt-text.

I'm talking about a wholly separate explanation in the post text body. Like, where you'd write the actual toot. Where you probably only have 500 characters. Where you wrote the above comment. It's there where I want to put the explanation.

The story behind this is as follows:

I keep reading from Mastodon users that alt-texts (yes, actual alt-texts in this case) are useful for sighted people, too, because alt-texts can give them explanations and help them understand what they're looking at. This means that images must not only be described, but also explained if necessary.

On the one hand, I keep telling Mastodon users again and again that explanations do not belong into the alt-text because there are people who can't access and read alt-texts; Mastodon users tend to be very defensive of using alt-texts to extend their 500-character limit by another 1,500 characters per image.

Still, on the other hand, this means that especially Mastodon users want images that they don't understand to come with explanations right away. In particular, neurodivergent people often need explanations, in-depth explanations even. It appears to have gotten to a point where posting an image that needs explanations without explanations is considered just as careless and almost as ableist as posting an image without accurate and sufficiently detailed alt-text.

At the same time, whenever I post an image of any kind, memes included, they're about such obscure topics that they need an explanation. Also, not everyone is always familiar with every meme template, so I have to give an explanation for the meme templates I've used as well. So I always explain whatever might need to be explained.

Summoning the Venus Butterfly (1947)

A surrealist painting by Salvador Dalí features a massive, centrally positioned butterfly with wings resembling decaying autumn leaves in warm shades of orange, yellow, and brown. At the center of the butterfly, a slender female figure emerges, adorned with green foliage and flowers.
