Here's the video from the talk I gave last week at the O'Reilly Strata conference on "big data" in NYC. The talk is called "Designing for Human Sensors, Not Human Barcodes," and it talks about the philosophy underpinning the "privacy bargain" we strike online when we trade personal information for access to services.
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.
