I personally give my good ol' buddy Noam a 10, even though his writing style certainly isn't for everyone, because what he does is very careful, very diligent, and very valuable. He's been a huge inspiration for me, and while I emphasize somewhat different things these days as an activist and changemaker, I do still believe in his general worldview and I deeply admire his focus on personal responsibility. He truly is a prophet of a kind: Not perfect by any stretch of the imagination, but very important and very noble.
