Identities are somewhat decentrallized, but it’s pretty different from ActivityPub. People can host user data separately, but it isn’t really an instance. It is technically possible to have other relays (basically instances), but requires handling all the data on bluesky to connect to it. It would cost probably 50-100k USD/year, and that number will go up as more people join or if there’s more relays.

There’s Mines3D on android, although the graphics are still 2d and it’s a pain to play.

Why?! The whole point of federation is to let people join communities even when they don’t have an account in the same server.

For people who’ve used lemmy or the rest of the fediverse yes, but most people don’t know that yet. If someone shares a post from your site with their friends or a facebook group, they’re not going to look into how lemmy works to sign up elsewhere.

1. people that are looking for a community in a niche interest, do not find it, and go back to Reddit.
2. people that are in a big instance and create (or sometimes, recreate) a community for a popular topic. This happens quite often and not because they were not satisfied with the existing communities, but just because they could not find them.

The idea of having topic-specific instances is an attempt to mitigate issue #2.

I’d prefer it if topic specific instances were more popular too. I just think that letting people making accounts tied to their favorite topics would get more people interested in joining them.

I feel a technical solution like federation pulling in lists of communities with would help more with discoverability.

Not my experience. A few examples:

• No one complained about the mods from !linux@lemmy.ml, yet I’ve witnessed endless discussions about moving away from lemmy.ml.

I’m not sure how that goes against what I said. That’s mostly people disliking the admins.

• Beehaw defederated from LW, so this forced users of these instances to “choose” between the communities and/or create accounts on both of them if they wanted to keep following the whole conversation.

Similar issues could happen even if users are separate from the communities. Beehaw could defederate your instances, and lemmy world could defederate programming dev or something, and people would need other accounts if they want to see everything.

• Personally, I do not want to join or participate extensively in communities that are on LW if we have a topic-specific instance for it. I know that I am not the only one.

Me too. I usually avoid lemmy world communities unless there isn’t an active community elsewhere.

New users to lemmy usually aren’t going to join communities if they can’t register there. And people who are really invested in a topic will want to have that domain for their account. You’re cutting off a lot of the users that would grow your communities.

I don’t mind the idea of a collective to handle a bunch of instances, but I feel like you’re going about it the wrong way. When the same person make a bunch of instances about a variety of topics, it looks as if they aren’t that invested in any specific community. From my experience, the most active communities start off with a few people who care almost obsessively about that topic.

Also the idea that communities can be ‘neutral ground’ doesn’t make sense to me. People will leave or join based on how the admins and mods run them, whether or not the users are hosted there. In some situations it might work out fine, but if anyone thinks it’s caused by how you’re running your sites, they may defederate from the whole collection.
