You and the GP are actually in agreement with the thesis of TFA (though not the specific argument it's making). TL;DR is unnecessary for two reasons: 1. If you're writing a piece in which "the journey" isn't important, then you should put your conclusions up front like a good journalist. 2. If you're writing a considered, long-form piece in which readers' appreciation of your conclusions is path dependent then a TL;DR is obviously counterproductive - if it's necnessary for a reader to actually read the piece, it doesn't make sense to reward those who skip to the end or didn't comprehend what they read. TFA took point 1, you and GP took point 2. Nobody (except Charlesmigli) has given an argument that TL;DRs have a place.
