Are you asking how link aggregation sites work? Or are you just noting that you're surprised at the overlap between the HN community and the Rust community?
I think the parent question, "What else is cool about it besides being written in rust?", speaks for itself.
I understand that there are currently a large number (or at least a vocal number?) of HN readers with an interest in Rust. I have been here long enough to witness Lisp, Haskell, Node, Golang, Julia, and even .NET Core all go through similar cycles.
However, Rust is the ONLY one on that list for which "___ written in Rust" is a nearly automatic trip to the top of the front page. It's weird. It feels like astroturf at times, and even if it's legitimate good faith then it's still overbearing.
Just...... is there literally ANYTHING noteworthy about "_____" other than the programming language it was written in? I'm not sure how noteworthy that is, by itself, even if you have a strong interest in that language.
