Churnalism: discover when the "news" you're reading is a press-release

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!"
