From the Kansas Memory project, a collection of childrearing public information posters issued by the Kansas State Board of Health from 1900 to 1920. I like this advice for how to give your kid fresh air: Don't put him in a wheelbarrow, you dope! Build him a cage!
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.
