Both. The community mostly does the former which is done on purpose and is their way of marketing the language for the best exposure and releases are announced simultaneously across all social media platforms. On HN, once it's appears in new, they all race to upvote it to the top.

The later appears to be applicable for its users who post blogposts like this one to be potentially used in interviews for jobs in Rust.

But then again it appears that the Rust community has hired a town crier to blast their trumpet about all things Rust almost every day right in your face. That is the most aggressive form of marketing I have ever seen for a programming language.
