I can't tell what your point is. If it's that this is not appropriate for HN, I disagree strongly. If posts relating to a specific technology were not allowed, HN could hardly live up to its name. For myself, this was one of the few immediately interesting things on the front page, despite having little more than passing knowledge of Rust.
I was just interested to know if it was interesting to people unfamiliar with Rust; no particular point about it being inappropriate to HN or anything like that.
Having contributed a small amount to Rust, I wouldn't have naturally posted this one to HN because I though it would be of little interest to folks outside the community, but I'm glad it has interested some people! If you are interested in reading more posts like this, they pop up sometimes on our subreddit: http://www.reddit.com/r/rust/
My point is, no one bats an eye when someone posts something that's only relevant to, say, the Python or Haskell community. Further, I bet there are a lot of people like me who aren't really rustites, but are interested enough to want to keep tabs on Rust's progress. Anyway, I mean no offense, only to encourage people to be bolder in posting. :) I'll go subscribe to /r/rust now.
