You know what, I like this idea I had in this other topic, so let's do this.
I really adore depth and nuance when it comes to otherwise mundane aspects of life. When people explore a niche deeply, they gain this ability to become a tour guide through (what feels like) entirely new worlds. Being able to pick out the tidbits of wisdom from the barrage of available information on a subject is so, so valuable. Trying to learn what's worthwhile and what isn't on our own can be daunting, overwhelming, and all-together unproductive. I figure as humans we only have the time to develop a handful of these specialties. But, when we come together, collectively we can all benefit and grow.
If/when I have the time/money some day, I'm going to spend it exploring these little niche corners and trying all of the wonderful things that you can only discover through years and years of searching. Whether that's food, or books, or electronics, or hobbies, or activities, or whatever! It's why I'm not a fan of surface-level things. I just know there are magical enthusiast/hobbiest versions of everything hiding in tucked-away corners of the world, and I don't want to have to settle for the basics.
So, what's your niche discovery that you think is worth sharing?
