Redditor Ventachinkway caught a photo of a homeless man conducting a clever exercise in behavioral economics disguised as an inquiry into the levels of spontaneous generosity as determined by religious creed or lack thereof.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
