My understanding was that 538 always sucked at everything except forecasting elections and discussing baseball statistics. And by "forecasting" I mean making a prediction of who would win Florida after a third of votes had already been cast.
But I have changed my mind. This new post is hilarious.
538 has mostly been trashed for writing articles where they take a simple time series, eyeball it to make a wacky point, and then do linear extrapolation with it until Kingdom Come. So what did Nate Silver do? All of the above.
This is obviously Native Silver doing satire of 538.
