I tend to compare the #nixos and #rustlang communities a lot, because that is my bubble. Rust seems so incredibly on top of things, in comparison. Just the general way they understand social dynamics, and the way they communicate.
For example, there was an incident last year where Rust leadership had to make a public apology. I went back to read that, and there's no perfect way to do it, but it seems way better than how Nix is dealing with the Anduril controversy. https://blog.rust-lang.org/2023/05/29/RustConf.html
