DJ Earworm has produced a mashup of Billboard's top 25 tracks for the US for all of 2007. The raw material is pretty poor quality (Top 40 has never been brilliant, but it's at a real low this year) but Earworm spins some gold out of the straw. Link (Thanks, Widgett!)
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.
