Emergency account of a not-so-average OpenSim avatar. Mostly active on Hubzilla.
Late, but still: I dare say that what Mike Macgirvin has done.
Mistpark/Friendika/Friendica looks like and is marketed as a Facebook alternative. But it comes with extra features on top like a built-in file storage, and its actual killer feature has always been that it federates with everything that moves.
Red a.k.a. the Red Matrix used to handle much like Friendica on the surface, but it introduced nomadic identity and permissions as early as 2012.
Hubzilla, into which the Red Matrix was turned in 2015, is probably the most powerful of all Fediverse projects. It was the first Fediverse project to implement ActivityPub, two months before Mastodon. And it was the first nomadic one to actually kind of take off.
Finally, the latest offspring of 14 years (plus two days) of development since Mistpark is the streams repository which isn't as feature-heavy as Hubzilla, but the most innovative one, and it's constantly evolving. It will be there first that nomadic identity and even permissions beyond what Hubzilla has to offer will be implemented in ActivityPub. And it's likely that this will happen this year.
Also, not everything has Mastodon-style reports built in. Not sure about modern-day Friendica, but AFAIK, Hubzilla and (streams) don't.
So if you're on Mastodon, you report a Hubzilla user on their home hub, and nothing happens, that doesn't mean that moderation is neglected to such degrees that Fediblocking the whole hub is justified. It doesn't mean either that Hubzilla's culture is so much different from Mastodon's although it is.
It simply means that Hubzilla doesn't understand Mastodon reports.
I know, but that limit is still deeply engrained in Mastodon's culture which seems to actually be built against mastodon.social.
Mastodon has the userbase, and - as you say - is the place where the serious discussion of accessibility takes place.
There's no discussion taking place.
Mastodon is horribly bad for discussions because the more people discuss something, the more mentions have to eat away on the 500-character limit.
Instead, there seems to be total consent for how things are done on Mastodon right now. Even though this way of doing things a) doesn't work in niche situations unknown to Mastodon users and b) make no sense if you take away Mastodon's limitations, e.g. everywhere else in the Fediverse that isn't Mastodon. Nope, no questioning the Mastodon way. How could you even.
A lot of Mastodon users follow hashtags, so including relevant hashtags (#accessibility and #blind seem like good starting points) might be a good idea. Tagging groups, such as @accessibility@a.gup.pe, might also help.
As I've already said, for someone who is not on Mastodon, it's pretty much worthless to try and discuss Fediverse post accessibility as applied on something that isn't Mastodon with people who are on Mastodon. And Guppe is practically exclusively used by Mastodon users.
One example: Many Mastodon users have stuck in their heads that you can't post more than 500 characters in the Fediverse. For even more Mastodon users, "alt-text" and "image description" are 100% mutually synonymous and mean the exact same thing. Image descriptions, no matter what they contain, always go into the alt-text. It's like a law of physics, deviating from which is unimaginable.
If you talk about describing or explaining something in the post text body, whoosh, it flies over their heads. No matter how much sense that'd actually make.
Not to mention that you have to keep every post and every comment at 500 characters or below, otherwise a large number of Mastodon users will pretend you aren't even there or mute or block you outright. I know that from personal experience. And there are things that simply can't be discussed in glorified tweets.
Also, Mastodon seems to only know two kinds of pictures. One, screenshots of social media posts. The stuff that requires transcripts. Two, simple real-life photographs, especially cat pictures.
Edit: I over-emphasized the point about reaching a broader audience. If you want to discuss a narrow topic but you don’t want most ActivityPub users to see it because you don’t value their input, I guess Lemmy is as good as it gets.
Ideally, I'd discuss this topic with people from all over the Fediverse. And I want these people to discuss it with each other within the comments section. Mastodon users who really care a lot for accessibility, who want everyone's needs to be catered to, and who are shooting for WCAG level AA, just as well as users of Pleroma, Akkoma, Misskey, Firefish, Iceshrimp, Sharkey etc. etc. who have much higher character limits in their post and users of Friendica, Hubzilla and (streams) who do not have a character limit.
I don't just want a bunch of one-on-one discussions between myself and someone else. I want to discuss such matters with Mastodon users and non-Mastodon users, and I want the Mastodon users and the non-Mastodon users to read and reply to what the other side has written.
I want people on non-Mastodon projects to tell Mastodon users who only know Mastodon what things are like on other projects. I want Mastodon users to tell non-Mastodon users how important accessibility is and which aspects of accessibility is how important. And I want to learn from this discussion.
I want to read opinions and ideas from all over the Fediverse. And I want users from all over the Fediverse to read these opinions and ideas.
And in particular, I want to discuss with them edge-cases in accessibility that go far, far beyond Twitter/Mastodon screenshots and cat photographs.
I wasn't talking about the dev side/Fediverse frontend development.
I was talking about the end user side, about the requirements to make Fediverse posts accessible, especially image descriptions.
Thing is, on Mastodon, it's pretty much mandatory to give a useful description for every last image you post, If your posts reach Mastodon, your images better be described sufficiently. But everyone's just got "the Mastodon way" stuck in their heads which is built around only having 500 characters in posts, and nobody can imagine there being images that are much different from Mastodon/Twitter screenshots nor cat photographs.
And everywhere that isn't Mastodon, nobody has even heard of alt-text or image descriptions, or if they have, they think it's another stupid Mastodon fad.
That's what I have mostly got on my mind.
Maybe you've overlooked that, but: I'm mainly on Hubzilla, not on Lemmy.
By far most of my connections on Hubzilla are on Mastodon. This means that my posts show up on a) Mastodon users' personal timelines and b) the federated timelines of lots of Mastodon instances. This, in turn, means my content has to fulfill at least some of Mastodon's cultural standards.
Also, I'm one of the few non-Mastodon users who do care for their reach on Mastodon. That's because I'm probably one of the few Fediverse users to explain to Mastodon users the Fediverse outside of Mastodon. This is not the primary topic of my Hubzilla channel, but someone has to do that.
But if even more Mastodon users or entire Mastodon instances mute, block or shadow-block me for repeatedly flipping the bird at Mastodon's etiquette and being unabashedly ableist, this becomes impossible because my explanations can't reach their target audience anymore.
Even when I post about my primary topic, 3-D virtual worlds, I rely on being read on Mastodon. For it is there where the chances are the best for there being someone who is interested in that topic.
