No matter how exotic a topic is, somebody will show up who has first hand experience and actually is an expert. And one of the nice things about HN is that usually when that happens, others do acknowledge the expert status and those contributions get moderated up to higher visibility fairly quickly. Interesting discussions often result, sometimes on quite surprising topics that might not be among the usual "core topics" for this forum yet still interest a lot of the same people.
