Someone else recommended it on HN. Still haven't read it; I'm pretty sure it will be amazing and I'm saving it for a long, boring trip.

I'm usually fairly focused, but when I started reading it I ended up spending the better part of the day reading the whole thing. Reading it is a very humanizing experience. Definitely enjoyed it.
