What's really great about HN (now I'm being sarcastic), is people who will nitpick at tiny things you say, and then reinforce their pedantics with "This is what makes HN great" or "HN isn't about this". I was just making a simple comment. Is that now allowed on HN?
When someone nitpicks at a tiny element of a larger post, that's pedantic. When all you posted was something tiny, however, you're inviting further inquiry by being unspecific and vague.
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.
