Imagine if you will a site where links are shared amongst a very tech-heavy audience. I for one think it's reasonable for the average HN reader to understand the sites linked to.
"If you don't understand it, you don't belong" is a crap attitude. They wanted to learn, if they didn't they wouldn't be asking what it means. What happened to good writing?
It's not about being tech-heavy, it's about specifically running a Linux desktop on a distribution where you're running a very modern software stack, and you're not using a bundled desktop, so you're in the market for a compositor built for Wayland.
That's just a very specific usecase. You can be extremely tech-heavy but if you run Windows then this wouldn't matter to you.
I'm a very tech-heavy guy, and no, I don't understand everything linked on HN because it's just outside of my scope. Anything with Mac OS? Couldn't tell you.
That's my point. If given a link to a random article about macOS details, I expect to be able to identify it as such, and not just be completely baffled. As a macOS user looking at the Hyprland page, you won't even know if it's meant for macOS, Windows, Linux, Android -- even the idea that it's software is only by implication.
