SO is intended to be a "reference" site ... unlike VBF which tends to be more ... conversational. On SO you ask a question, get an answer. It's isolated and directed specifically at the question ... there's no discussion whether the approach of the OP or the responder is the ideal approach... Here, it's a bit more engaging, we're going to question the approach, we're going to dig deeper. Attempts at doing this on SO get those posts dropped.
