The Browser is one of my new favorites for finding reading for the train.
It’s jammed with editors choices of great reading (and they’re great) and has something called, FiveBooks, which I’d like to steal if I had any time. They interview smart people about something those people know about and get suggestions for five books people should read on the topic. It’s tremendous.
If you go there once a week, at the end of the year you will be 520x smarter than you were at the beginning of the year. I promise you.
