Catfish noodling is a fishing technique that involves sticking your arm into a catfish hole and waiting for one of the big monsters to latch onto your arm as it attempts to escape.
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.
