I upvoted it because if the reader reads through it, they will leave with more understanding of the system stack than they started with. As someone who has been deeply involved with teaching a systems class, that's near-and-dear to my heart. I think it succeeds in that goal. I'm far less concerned that it doesn't actually emit "hello, world".
That it fails at being an introduction to assembly is, I think, missing the point. It doesn't try to be. It's just trying to demystify some of the system stack.
As for HN itself, I've known for a while now that there's a pretty wide range of people here. While I think the percentage of people will almost no systems experience is more than it was a few years ago, the number wasn't zero a few years ago, either.
