Maybe part of the exodus of reddit users are coming to HN?
It seems like HN has become more political in just last couple months.
This is ... often a strange and uncomfortable place for me to be. I'm geeky, and work in tech, and I tend left wing and have absolutely no interest in finance, and have a deep deep distrust of "tech bros" and startup culture.
I've also found that I have a tendency to come across in online discussions as far more strident and argumentative than I really am, especially when I'm tired. That's something I'm working on.
