FWIW, I have a $20 pair of Sony unknown model # headphones I picked up at Ross. I bought them because they were over ear and cheap not because they're white, have Sony logos on them, or because I wanted to make a statement about what group I'm in or not in.
But yeah, HN is also very group membership oriented and people spend extraordinary amount of time to build things with things that signal that they're part of this group. The trope is "yet another photo sharing app" right?
