You're getting the right idea by the end of that comment :)
Bear in mind that HN began as a community of startup founders and enthusiasts, and even though the audience has broadened, it's still part of the culture to be charitable and supportive to people who are just starting out and trying to get something off the ground.
Not everyone entering the startup world has an MIT PhD (we hope!) and the ability to write content that has both technical depth and literary polish.
We all have to start somewhere, and the only way to start getting better at something is to put something out there and see what comes back.
Critique is fine, but we can be constructive and encouraging to help people improve - just as we'd hope people would to for us if we're taking a risk on trying something new.
