There are several rust instances: https://lemmy.ml/c/rust, https://programming.dev/c/rust, https://lemmyrs.org/, and probably more. Why aren't they linked together, so that you see posts from one instance in another and can post and comment in one instance from an account on another? (I get there is e.g. https://lemmyrs.org/c/rust@lemmy.ml, but you should see and make posts from https://lemmy.ml/c/rust on the page https://lemmyrs.org, not a specific subpath).
Even better, why can't Rust lemmy link with rust kbin (https://kbin.social/m/rust) link with Rust discourse (https://users.rust-lang.org/) link with Rust Zulip (https://forge.rust-lang.org/platforms/zulip.html), so you can see and make posts on all instances from one?
This is what I initially thought the Fediverse was like. Right now it honestly just seems like many people running completely different servers and communities using the same software.
(This could even help with the decentralization aspect, because ideally the content and accounts would be replicated. So if one instance goes down, its content is still on connected instances, and possibily "ghost accounts" from that instance which let users there continue to post).
