Look I don't think it's the medium really. HN is quite similar to Reddit. Reddit I wouldn't consider to be that healthy as it's really driven by strong politics and it's sometimes impossible to express an opinion reasonably without getting into trouble. The big difference: the people. I think HN is a healthy community because it consists to a degree of like minded people. Smart people with an interest in programming and technology business/startups. Whereas Reddit is everybody from teenagers to farmers. That's not to say I dislike Reddit. I was on that site many years.
