A little while ago I wrote about the recent Vafa paper on The String Landscape and the Swampland, as well as about postings on the subject by Lubos Motl and Jacques Distler. Lubos’s contribution to the subject was introducing the new terminology of “s**tland” and “f**kland”. Jacques’s was to claim that you can’t get anything you want out of string theory, his main example being the supposed impossibility of getting one or two-generation models. This didn’t sound right to me, but I’m no expert on the subject. Well, it turns out Jacques had no idea what he was talking about, which Volker Braun pointed out to him in a comment.
Given the high quality of the comments by Lubos and Jacques, I was surprised to see that if you look at the trackback page for the Vafa paper, you’ll note that trackbacks to their postings are there, but not to mine, which evidently has been censored. Not all my trackbacks have been censored, but it appears that, as far as papers about the Landscape and the Swampland are concerned, the arXiv policy is that trackbacks to postings about the subject that are ignorant or scatological will be allowed, but not ones critical of the whole idea.
Update: I’ve heard from someone associated with the arXiv that it’s not their intention to allow trackbacks to my postings to be censored and that part of the problem has been both difficulties they’ve been having with new software and with deciding how to handle moderation of trackbacks. A trackback to my posting on the Vafa paper is now there. Jacques Distler has updated his posting to include an explanation of Volker Braun’s proposed construction of a one-generation model.
