Can background music make you smarter?Amen to that. I love working in energetic places like subways, cafes, airport lounges and hotel lobbies. I don't like people actually interrupting me with questions or whatever, but I love working in busy places where everyone is doing her/his own thing. Link
The more you can concentrate with background noise, the more it strengthens the brain. Isaac Asimov used to set his typewriter up in stores and other loud places to work. His claim was that you get really good at writing when you’re in a crowd. You want to be energized by that background noise, rather than distracted.
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.
