Why I Moved from Havolim

Although it was a perfectly good and  appropriate name (הבל פיהם,  חבלים היו לי בנעימים, אדם להבל דמה, מאן דנפח מגרמיה נפח, among many others,) I moved the serious Torah to Beis Vaad because, among other reasons, I was looking at this (115) bizarre question in the Rogotchover, where, at the second sentence in the second column, he indicates that ואל ידבר הבלים מספרי המלקטים הבורים is not just a modern phenomenon.  The shailah reminds me of the chassan that asked me whether there would be an issur of negi'ah if he wore gloves.  (Of course it was a silly question; the issur is lo sikrevu, with gloves or not.  It happens to be relevant by yayin nesech too- see Igros YD II:51, where Reb Moshe assers, and of course in hilchos lulav and kodshim.)  Good thing I told him it was assur, because the Rogotchover's case would have been the next question he would have asked.
