I've never written a single line of Rust. But I try to keep up on it since it's one of the most interesting and ambitious languages to come along in a long time. And I will say this, I think the community is doing a great job of being transparent and making it possible to follow along on the side. If it's anywhere near as well-run on the inside as it seems to from the outside, then I think it will serve as a poster child of how to develop a language in the open and build up a community around it.
