Hipsters are keeping a lot of the old, interesting technologies (sort of) alive. So I suppose they do serve a purpose in the universe. But when they get jobs and mortgages and stop being hipsters - which most of them inevitably will - these thing may be forced to die a second death.
But for now, yes, all hail the hipster. Raise your can of cheap beer with me, rattle that long beard! Huzzah!
