Free Rice

Although in the back of my mind I suspect this is actually re-directing mental energy toward comparatively less productive purposes, which in the long run would reduce output available to be redistributed toward reducing global hunger through more traditional means, I nonetheless agree with TNR's Britt Peterson that Free Rice is a small act of genius, by allowing people like me to simultaneously avoid real work, feel smart, and--crucially--feel like we're saving the world in the process. That's like the holy trinity for left-leaning policy types who tend toward procrastination.
