This embodies what 538 and its defenders miss about 538's appeal:
People didn't come to 538 for explanations on subtle points of statistical literacy (although those were provided). They came because, for whatever reason, they wanted to know who would win the election.
People not trained in statistics treated like the scoreboard at a football game- it's always better to be winning, but score is a near perfect predictor in the last minute.
Once 538 stopped delivering perfect predictions and started delivering "Actually the difference between 1% and 30% are way bigger than you think" lectures, the appeal disappeared. There are better places to learn math from.
Speak for yourself. That's not why I read FiveThirtyEight.
The purpose of FiveThirtyEight was never to be an oracle for the average person. It was always a deliberately wonky site for a wonky audience. They were very clear about that in the articles they published and topics they covered.
