But it does contain pertinent and new (to me) information: first, that the original "not worried" post was not written by any kind of nuclear authority (I'm sure I'm not the only one who assumed it was); second, that it has since been taken down; third and most importantly, the interview from the Tucson paper with someone who has deep experience in this area. (Yes, the wording of the post is inappropriate and goes against HN guidelines, but that doesn't change the above.) A word in Josef Oehmen's defence: what he wrote was an email to a relative. It isn't his fault that the relative published it, hyped up his credentials misleadingly, and sent it off into viral-land.
