Mike sez, "We had several of these exciting automated milk stores around Tulsa in the 1960s. You plugged in a few coins, pushed the button, listened to the mysterious robotic sounds from within, then out dropped your half-gallon carton of milk."

(Thanks, Mike!)
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.
