I've removed the
trivia tag. In my view it veered on the wrong side of meta-tagging to start with. I also always read it as a descriptor meaning something like "this is the kind of question that might be asked during pub quiz", and it was being applied to questions like How are the Lego instruction manuals made? which don't fit that at all. In a broader sense, everything on this site is trivia.
I replaced the ones that actually were trivia with records, all three were about the "biggest" something; otherwise I've just removed the tag.
