Hopefully, I'm not breaking any rules by posting this here!
I thought that instead of every community being on the main lemmy.ml instance I'd host a different (dedicated) instance for refugee rustaceans to get a hang of the fediverse.
As long as you're already here then yeah you can just subscribe to https://lemmyrs.org/c/rustlang. lemmyrs.org serves as an instance for those who haven't yet joined the fediverse to help keep the load off of the main beehaw/lemmy.ml instances.
If there's enough traction in the rustlang community then lemmyrs.org can serve both as the instance to join fediverse as well the main rust community on fediverse. I think its too early to tell.
