Did I break HN post regulations for this comment? (Just trying to figure out why I had 5 down votes in the interest of not breaking it again if I did).
Your comment looks pretty innocuous to me. Only thing I can think of is that it doesn't add much to the conversation. Members may have downvoted for lack of substance. Adding reasons you found it interesting, pointing out things in particular would make a good contribution to the discussion. It's speculation, but I hope it helps.
