The original paper is discussed in this thread: http://forums.phoenixrising.me/index.php?posts/360343/. I see a few people have posted about the follow-up paper. However, that's all the way down in message #149. I missed the opportunity to post an e-letter on this paper (they have to go in within three months of publication) but would like some observations to show up on search engines and the like. So thought I'd be best to have a separate thread.
