Ah from my experience on HN derailing topics is acceptable as long as it stays constructive and new things are said. Also no one is forced to read a thread that already starts at ~3 levels deep, if he doesn't like the topic. It's really easy to just collapse that. I often really enjoy some threads that have derailed heavily, but tell me knew interesting things in a well written way. I have seen the peace memorial. The children memorial close by left the most lasting impression. Ringing the peace bell was also a very special moment. I only had Okonomiyaki in Osaka. Not cooked in front of me, but served on a hot plate built into the table and finished at the table with what I think was mayonnaise and dried tuna. It was good, but I will have no chance to visit Hiroshima again to compare.
