Good posts on software more reliably get to the top of lobste.rs than on HN in my experience. Whereas on HN you're competing with a wide variety of topics. Lobste.rs is pretty focused on just hardware/software hacking.

I don't mean that negatively. I'm glad we talk about varied topics on HN. But it's also nice to have a place that almost only talks about software/hardware.

Sometimes I've thought about starting a "software internals" forum but then I remember that's basically exactly what lobste.rs already is.
