Interesting read. Honestly I never took stock of my "social network occupational diversity" but after reading this I feel lucky. Almost no one in my circle of friends shares the same industry, let alone job title. It has a wide range of age groups -1 decade / + 2 decades which may explain it. I'm rural so age isn't very homogenized and any local bars or clubs have a wide spread. We don't talk much about work... I'm now wondering if this is because our professions don't overlap.
