You changed the subject from the original topic to the status of comments on HN. That's meta, because it's an HN comment about HN comments; it's a tangent, because it's a change of subject; it's lame, because meta threads (while superficially exciting to insiders) are highly repetitive and self-referential, and also are nearly always full of inaccurate information as people invent explanations for what they think they're seeing.
Does that make sense?
