Seems like every hobby is too obscure for most to care at the level I do. Sim racing, rtlsdr, self hosting, ANY kind of motorsports, home automation, blogging, DND, video games… At the surface these are not too obscure but I find very few people in my day to day life that care about them in detailed way
I just posted a similar response but I think the issue, at least for me, is how deep into the weeds I get with each subject. Anyone can be into coffee for example, but it’s the ones who do the research and watch the videos about the subject in their free time, that make a simple thing such as coffee become more of an obscure thing. 🤷♂️
