Sounds like a hugely echo bubbly view of the popularity of rock climbing and the HN demographic
Indoor climbers are all software engineers in some cities. In Seattle and San Francisco in particular, nearly everyone I meet there is also a software engineer. The gyms are so expensive that they are the only ones who can afford it with FAANG subsidies.
Outdoor though you're right, totally different demographic and very few of them are software engineers.
This is what turned me off from rock climbing. I couldn’t handle the monoculture version of it in the Bay.
I heard a lady in my indoor gym loudly complaining about an outdoor spot being full of tech bros. Seattle area.
I climb, but I doubt 5% of hacker news does. In fact, among software engineers (few of whom rock climb in my experience), I suspect the ones who climb are less likely to be on HN
If all my joints worked the way I would like I’d be spending half as much time talking about my hobbies online. It’s what I do in the in between times.
