Eh, I keep those circles separate. Programmers usually don't discuss or care about literature in my experience. Like any hobby, just gotta find the people that do.
Self-fulfilling prophecy. If we shut down the conversation about literature when it starts, then yes we'll never discuss it ;)
I'm always pleased to see posts on literature show up on the HN[0], but often disappointed to see so few comments. But enough people are up-voting them that they do regularly appear on the front page, so there's clearly enough interest around here.
Self-fulfilling prophecy indeed, and also very self-limiting. Personally, I got some of the best fiction recommendations from people here on HN, and I'm very thankful for them.
