That's awesome to hear! I've had similar experiences with Elixir. On the IRC #elixir channel, I've more than once seen Jose Valim (the language creator) or Chris McCord (Phoenix head honcho) answer relatively inane questions about CSS or beginner questions about Elixir. Always felt heart-warming to see, and made me try and actively help out more so those dudes can focus on their work!
I still don't quite understand what makes Rust community this way, but it's one of the best things about the language.
