This is an excellent presentation by Evan Czaplicki about how open source / online community behavior, with lots and lots of great history. Highly recommended.
We dipped our toes into political activism today, joining the Women's March event being held in our hometown of Keene, NH. A friend of my wife's made her a hat, which I wore when we were walking back to the car. It was a good event, and it's helping our kids start to see beyond their privileged positions in life.
