Deadline is a Facebook news quiz application. We had a team of editors who'd write about 50 new questions a day based on current news stories coming in through the wire. It was an attempt to engage people on Facebook with current events in a fun way. It's setup so that you could also challenge your friend's news knowledge. It got a few good reviews like this one from the site Apprate. If you're interested in playing the quiz, click here to view it on Facebook.
