It was not there an hour ago - I would like to think that I was the impetus, as I saw it right when he posted and immediately replied: https://twitter.com/#!/andrewpbrett/status/56503853184598016

I have no idea but on at least one occasion someone changed what their article said after I remarked on it on HN. HN is pretty well known. I wouldn't be surprised if they updated it because of your remark, as appears to have happened once in a different article/blog because of a remark I made (thus making me look "dumb" at the time).
