People that stacked Blinkist
Despite the fact I love reading (and also have a weird propensity to think I haven't read a book unless I finish it front to back), modern non-fiction can get pretty monotonous in the repetitive way it tends to be written. So I like being able to just get the keys easily.
Blinkist gives you 15 minutes summary about many books. For free, you can get a daily summary. When subscribed, you have unlimited access to summaries. It gave me a good way to learn much in a timely manner. Meanwhile if the summary was really good, I would get the book!
