I've never heard of GiveDirectly.org...but on visiting the site I'm extremely impressed. I love these P2P style workarounds--Uber, Lyft, Airbnb, Kickstarter, OpenBazaar, BitCoin, etc. P2P systems like these are releasing humans in ever greater numbers to attack poverty via freeing the mechanisms of wealth creation to anyone with a net connection and a smartphone (or a Raspberry Pi).
What a beautiful, peaceful, and momentously meaningful assault on both poverty and global force structures.
Cheers Remlaps!
