That's the thing about apps like Blinkist - if the book can be condensed to fifteen minutes, it's not worth reading. If it can't, then I want to read (or listen to) the whole thing, not a summary.
I'll be the first to agree that a lot of books in topics like business strategy are too long. But IMO the ideal length is probably more like 100 pages than a magazine article much less a 1,000 word blog post or a listicle. Context, examples, background, etc. all add to a basic idea in a way that makes it easier to remember and understand.
