I got a subscription to Blinkist this year and use these ~20min audio summaries to determine if I think it is worth slogging through the whole book for more detail. It rarely is with modern non-fiction. I read most non-fiction to absorb information and learn new ideas, not for the joy of reading - that's what fiction is for. Of course the genre of non-fiction book is usually indicative of how much it is full of blaa blaa anecdotes, etc. Blinkist is at its best when listening to self improvement for example.
