[Blush] Thanks for your kind question. Let me first of all say that there is a lot that is discussed here on HN that I know nothing about, and in threads on those topics, I am in lurk mode, learning from the rest of you. So thanks.

On some topics, I have a different perspective just because I am older than most people here, so I remember history that other participants have to read about. Genetics research to be a responsible popular author about that research is part of my work, so this topic was work-related. I got lucky over the weekend, because I had just looked up the human population research articles to get ready for some contentious editing on Wikipedia, and thus all of the sources were at hand. Some of the other topics I comment about are also work-related, or related to my former work or my higher education degrees (neither of which were in computer science).
