Not trying to cast any doubt here, but how do we know this is officially done by the KDE team? I can't find a link to kde.social from kde.org. Even their matrix server is on kde.org.
Before you had to fiddle with the markdown link manually. As of v18, you can just type out the name of a community in the [email protected] format, in plain-text, and it will become a working link.
Currently if the community hasn't been discovered by your instance then you'll get a 404 error like I just did, apparently it's a known thing and you need to search for the community before accessing it, see here - https://github.com/LemmyNet/lemmy-ui/issues/1335
Do they need to approve each and every instance manually? I thought it would happen automatically as soon as someone is trying to subscribe to a "channel" of another instance. No?
I'm not familiar with the exact process yet. But doesn't that mean if you wanted to run an unfederated instance, you'd need to manually block every other instance there is?
Because it's better in term of health of the fediverse if we don't end up with only a few big instances like lemmy.ml. Also people can interact with lemmy.kde.social while not being on that instance
