I guess my main question is what is pg seeing that he doesn't like? He stated that comment quality was 'higher' after he turned this on briefly. I honestly have no idea what this means as it lacks specificity. From there I went with what the main complaints of posters in this thread and the other thread were complaining about. Vacuous comments, puns, and the like. I must admit to a high tolerance and enjoyment of witty zingers, so long as they don't dominate the discussion, so that colors my view re noise/signal.
