This must be the least exciting response... because I suppose there are many like me, who have a bookmark where every post that mentions Rust is listed. Like this one. So the same reason you got quite a lot of responses is the same reason why many posts get voted on: they get eyeballs early on, so the HN algorithm promotes them to a wider audience. Besides that I assure you, there's lots of interesting and unique things happening in the Rust sphere, many of which don't make the front page.
