I hope my previous comment didn't come across as me suggesting that the paper shouldn't be scrutinized because it comes from an established research group. Of course, it absolutely should be and double blind review is a helpful mechanism for achieving this.
One possible reading of the parent comment was an attack on the researchers. Of course, the parent probably didn't mean it that way but it might still feel hurtful to the authors and I wanted to clarify it. :)
It was an attack on HN'ers blindly upvoting things from arxiv, because most HN readers do not properly scrutinize postings from arxiv or take it with a grain of salt.
I was well aware these were actual researchers. Your comment probably didn't help very much here because most HN'ers, again, will just see that the authors are PhD's or from a decent group, and assume it's a legit paper.
