Generally today a hipster is someone who jumps onto social trends they don't know anything about because they are different from the norm. Often the idea is that they don't care about the thing itself, but rather just being perceived as different. But I'm a long time linux user, and in my head if a hipster is going to try linux it's way more nuanced, like real hipsters (and real linux users). You'll have the dude who tries ubuntu just so he can say "i use linux" to his friends with Macs. You'll have the dude who asks his bandmate who's been using linux for a long time, so he tries Debian, but then gets frustrated and stops, because the "cool factor" isn't enough. And then you'll have the hipster who goes like all in on NixOS or something and makes it their entire identity for awhile. I use arch btw
