I would have thought so. But you’d be surprised how often it can crop up. Somebody wears an old hat or shirt with a logo, or someone complains about a change at work or whatever.
It won’t be often, but I’ve run into OS discussions maybe three times this year, and I’m fairly antisocial.
9/10 it’s going to be someone bitching about win 11, and someone else saying “hey, south uses Linux something-or-other, go ask him.” And then the conversation happens.
That other one time is usually tangential, where I’m talking about writing and the conversation moves to the programs used, which leads to questions about why I use libreoffice, and the fact that I use it on mint as part of explaining my setup.
Now, I don’t use arch, nor do I usually bring it up outside of a few friends that have abandoned windows. But I have run into a few arch users here and there.
