Here's an Ignite talk by Hilary Mason, chief scientist at Bitly, explaining how she scraped data from multiple sources to create a service that locates NYC's most optimal cheeseburger, using an algorithm that balances out price, proximity, and sentiment analysis from various review sites. As Mason points out, this isn't about cheeseburgers, really: it's about the power (and limits) of cross-referenced data.
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.
