pg, the site founder, observed once that longer rather than shorter comments tend to be valued by other participants here (as judged by comment karma scores). The subset of HN participants who read my comments appear to share this opinion, as my longer comments do tend to gain more karma than my shorter comments.

To explain to you the specific reaction to your one-sentance comment (great-grandparent here, immediately below the submitted article link), I really couldn't tell for sure if you were being ironic or meant the literal meaning of the sentence you posted. A longer comment usually makes that of issue more clear, which is important in a medium where we are not speaking face-to-face and seeing each other's body language or hearing tone of voice.
