I don't think the quality of the home factors in, but I think you make an excellent point about HN'ers being highly self-motivated in terms of personal projects. They're less likely to be spending their time at home just watching endless TV or Instagram scrolling. So I think you're right, it doesn't generalize to the larger population at all.
