My father was an unnamed DG marketing executive in the book, who joked that his greatest career regret was asking Kidder to be unnamed in case the book wasn’t any good (it won Kidder the Pulitzer). I’ve been meaning to go through his old notebooks, as he took detailed notes on everything, to see if there is anything left from that era.
I joined DG in their last days, largely due to kidders book.
Also, I really liked DG/UX, for reasons I no longer recall.
The only thing I can now think of is using it as a personal therapist. Or asking how to approach their kids. And they're a bit embarrassed about it, because it's still outside the Overton window -especially on HN - which is why they aren't sharing it.
If someone has different usecases, please do prove me wrong! Maybe I just lack imagination.
