Right now there is a bit left to be desired when it comes to lemmys accessibility features, but it’s a good idea to be mindful of the fact the fediverse and its platforms tends to have pretty universal accessibility features that will likely come to lemmy sooner rather than later
Fedi seems to be really great for accessibility from what I’ve seen. At least I’ve never never interacted with so many visually impaired people before joining mastodon. So I’d say that culture is working.
I believe there’s a nice way to go about (honey v vinegar, etc), but generally yeah, it feels really good to be in a virtual space that is so welcoming.
