People like to post their opinions to the world. It feels good, and feels like you are being "heard". But for most it stops there. Not many care to debate online because a) it takes time and energy vs posting something you've had in your head for a while and b) they know almost no one changes their mind online. On top of that, HN doesn't notify you when someone replies to your comment... so maybe they just forgot.
