Oh My Freakin God, the Gavster has a book and it's called "Citizenville." [1] And it's all about how government isn't a vending machine and we should look to the private sector to do everything much better with a lot of technology. I suspect there's not a lot in the book about homelss policy or poverty or income inequality, since those can't be solved with an app. Check out the trailer. Gack.
