Even if I want to read the entirety of a piece of long form writing I'll often summarize it (with Kagi key points mode) so that I know what the overall points are and can follow the writing better. Too much long form writing is written like some mystery thriller where the writer has to unpack an entire storyline before they'll state their main thesis, so it helps my reading comprehension to know what the point is going in. The personal interest stories that precede the main content always land better that way.
