>Maybe because a lot of people on HN are small business owners,
A lot of small business owners who also happened to work for a union and had a bad experience? That seems like a lot for a site largely filled with software developers. Is HN more mainstream than I'm giving credit?
HN is not mainstream but has a diverse audience. The subset commenting on any story is a self-selected group that likely has more experience in or devotion to the topic. Find a thread about math or physics and you’ll find an outsized representation of mathematicians and physicists commenting; does that indicate the site is full of mathematicians and physicists? No, they’re just self-selected to comment. Same here.
