I actually made three new friends on new years eve completely through mentioning Linux. We were at a party and I had a really bad year last year so I was rusty in the “talking to people” department, the few people I knew there, who are indie games devs that don’t use Linux, said something (can’t remember exactly what) that made me reply with a Linux joke and those three people moved their chairs closer to me with a “ooooh, a linux nerd, let’s fucking go” energy. We went on such a nerd dive that they party host told us that we aren’t allowed to talk Linux anymore or we’d have to leave.
We talked a lot more through the night and had to really concentrate to not get thrown out, haha.
