Rust is promising, without a doubt. But it's not yet truly usable in the same sense that C, C++, Java, Python, Haskell, Go and so many other languages are.
Maybe it'll start to get to that point once 1.0 is released, once we see at least some language and library stability, and then perhaps some adoption. But that just hasn't happened yet.
I do, but I do that on Twitter, because, as you've found out, HN will downvote you into oblivion.

Ah ha! Sorry, I didn't see that: usually, new users are in green. (also, your account is 163 days old?) If you haven't checked it out, you should check out the community guidelines: http://ycombinator.com/newsguidelines.html
For what it's worth, I am not trying to 'bash [you]'... but I don't think this was a great comment. Try to keep them more substantial here. Different forums are appropriate for different kinds of discourse, and short little comments are generally not taken very well here.
The same happens to "+1", "thanks", and "interesting!" comments. If you can't write more than two sentences, you probably shouldn't post.
So although early adopters might not get any useful software out of learning Rust at this stage, they might indirectly improve their future Rust code by having a small influence on the direction of the language.
