In a nutshell, here's what Blinkist does: they have smart people read popular business books and summarize them for you, so you get the good stuff (basically bullet points that they call "blinks") in a very short amount of time. It's great for those of us who want to keep up but don't have a ton of time for reading. You get the gist in a quick, easy to read format.
But... As we learned from Made to Stick by Chip and Dan Heath, a good story goes a long way to helping you remember the lessons from most of these books. That's what is missing if you do a quick read of a Blinkist digest. The ones I've read so far - no stories to help you remember the concepts... :(
