For example, I’m sure the average joe doesn’t know just how expensive calligraphy pens can be, or how deep the rabbit hole goes on video game speedruns.
It’s infectious too. I REALLY want to get good with one! and don’t get me started on the absolute craziest style: chorded keyboards! Insane!
Stenographers usually use something pretty similar so I doubt it. The ones I’ve seen (to be fair, live captioners, not stenographers) use something that’s closer to a piano than a normal keyboard, and it types full words rather than letters, but also has a regular typing functionality. Pretty cool to watch honestly.
