Nicko from the Sunlight Foundation sez, "I thought you'd be interested in a new browser extension and webtool from the Sunlight Foundation called Churnalism. It extracts article text from any site you'd like it to run on and compares it against a corpus of press releases, articles from Wikipedia and much more. If a significant amount of text from what you're reading matches something in our database, an alert banner appears on your browser and you can click through to see a side-by-side comparison. I imagine every editor would want to run this on their stories before they publish!"
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.
