I've pretty much taken to automatically buying any book anyone recommends on HN[1]. So far it's lead me to a few interesting books I wouldn't have read, for example The Overstory is the most recent one.
Thanks, I am not the orig creator but working with them on this as they are amazing (he even weighted it so it is based on HN Karma). I added RSS to my list of features, but not sure on ETA. Hit me up at ben@shepherd.com and I can update you once I get it added.
I love Five Books (their long form format is fantastic)! Agreed, I am hoping the emergence of Bookshop.org helps a lot more book/reading related sites make enough money to flourish.
It is so great I'm already paying https://fivebooks.com/ every month for it :-)
Seriously, though, the more the merrier when it comes to reading and recommendations if you ask me!
