The HN audience is not perfectly reflective of wider society. One obvious example is that people on this site tend to be more technically aware than the wider population, but that's not the only relevant characteristic. The userbase here tends to be technical, tends towards (or is at least dominated by) particular political positions, and seems to be much more literally-minded than other online communities.
