With the barriers to entry that Lemmy has it’s not that unlikely. It’s like an incel going onto 8chan and saying, we can’t all be the most edgy people we know.
According to this website there are only around 40-70k daily active users (monthly vs semiannual). If you look at total users we’re sitting on about 1.3 million with 11 million posts per day and 23 million comments per day.
So 0.015% of the world population on an obscure site which is not mainstream accessible.
EDIT: Just because you were one of the smartest people in your class doesn’t mean you are “smart.” I would argue that it says more about the other kids in your class than it does you, most people are fucking stupid.
No, it’s just a familiarity thing and not even rare. It’s like switching between metric and imperial units, if you’re used to seeing something in one format it can be jarring to switch it in your head at a moments notice. A lot of people in the US use 24 hr time if they have a job relating to documentation or if their working hours can cause confusion.
For example, I have a client that has to document received material and they are open from 04:00 - 22:00. They use the 24 hr format because it is common to receive material at both 04:00 and 16:00 and having to make an extra column to type am or pm on their logs is stupid and is just another opportunity to make a mistake.
It’s really not a big deal to anyone, if you get a job that uses it then you switch your phone and within a week or two it’s second nature. Every blue moon someone will notice that all your clocks are set to a 24 hr clock and someone might ask why or what you do to need it, but that’s it.
