I always took HN to be a forum for people either starting up a business or into "hacking" things. Of course many software people visit here, probably because many fast-growing businesses over the last 20-30 years have been software based, and/or many products and systems that people hack have a large software component. But HN isn't specifically for software developers as far as I know, and people hacking for growth in the property business shouldn't be classed as "non-developers" on Hacker News.
