Here's a great reason that the (on-again/off-again, oft-bandied) NYC ban on subway photography sucks -- breathtaking and comic photos like this one from Flickr user gothamistllc of the waterfall at Penn Station last night.

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.
