This wasn't the case in the older thread. I've seen you mention that you think HN hasn't changed that much but I think juxtaposing this comment thread against the older one is illuminating. HN has drifted more toward a general news site than anything particular special. Like most news sites, comments are characterized by short, overly emotional comments that argue in borderline bad faith. Comments aren't particularly interested in discussion but instead just cathartic emoting.
