I've generally found the Julia community less welcoming than some (Rust, Python), although much better than the "classics" (C,C++,Java and friends).

For example, picking the first question I can see on discourse (which isn't a clear technical question, it was number 3) is "What is the status of debugger?". The first answer is "I've used Julia for 3 years and I don't need a debugger" whereas searching for similar questions on the Rust discourse tends to find answers.

This isn't a complete investigation, it might just be me generalising from my small number of interactions with the Julia and Rust communities.
