> I read informative articles on HN everyday that have "ass" "fuck" "shit" or something like that in them. It's a very popular pattern for article titles. I guess we like it?

Not me. I feel that they contribute to the atmosphere in a negative way. The problem is that you can't dismiss these articles out of hand, they sometimes contain valuable insight. That doesn't mean they are to be liked for their titles. I'd prefer to see that as an 'in spite of'.
