The METAR Board has always attracted an eclectic group. Interesting and entertaining off-topic posts are a feature of the board, not a bug.
That being said, please mark off-topic posts “OT” if they have no investment impact even if they could impact economics eventually. (Such as the experimental scientific advances that @qazulight posts from time to time.) Please mark a post “Totally OT” if it has zero conceivable Macroeconomic or investment impact.
