I'll speak as someone who is part of the problem. As groucho Marx says, I wouldn't want to be a part of any club that will have me as a member!
HN is a victim of its own popularity. Things just get diluted and more mainstreamy by people like me, who are perhaps hackers in spirit but don't have much to show for it.
I work in IT at an international company everyone knows the name of. I've got a garden and there are meals in my fridge made of meat from pigs I raised. I've got furniture in my house my wife and I made years ago in a different state.
I'll submit random articles, but never a show HN. How could I? Woodgearsca built a woodworking shop out of his woodworking shop. No one cares about the tables I built. I try to speak only when I know I can contribute, but im very unsure i raise the quality here.
