Why does anyone comment on the stories posted on HN? Why do we have leisure activities? I don't think that anyone is commenting on HN in lieu of learning, spending time with family or friends, or pursuing a career. (Though many may be procrastinating at work!) I think the request was a less a demand, and more a polite suggestion for more content of this nature. No one will banish you from HN if you don't participate, but the site and its users might reap the mutual benefit if you do. Also, I think there is something to be said about the whole "learning as you teach" mentality. Often times I find myself explaining something (which I've done a hundred times) to someone (who has never done it before) and I catch myself saying things that I had not paused to reflect on before; or, I find myself finding even better ways to do things as I explain them to someone else. Those are the sorts of benefits that might be in store for yourself, without any consideration to mutualistic benefits.
