indeed, there are some acquaintances who consume books 'filtered' via blinkist ^^). all in the hope of claiming in their conversation circles of how broadly read they are.
Actually, a friend asked me why don't people read/listen to good summaries (like blinkist) but read the whole book? I read the whole book, but I have no answer for him. Many non fiction books have a single idea with many pages of examples. Say if you want to read the 7 habits of highly effective people, why not just read what those habits are? Why do you have to read through all the examples?
