I think this would exist in editorial. It would be different from contests.

My ideal use for them would be, say, a weekly news quiz that our readers could take on our website based on our content.

Here's an example of a more simplistic presentation of what I'm talking about: http://www.chicagotribune.com/news/nationworld/sns-quiz.triviaquiz

And a fancier one: http://www.pewresearch.org/quiz/the-news-iq-quiz/

And here's a link to a quiz on our website that I "faked" using a collection asset (this one was enormously popular): http://www.capitalgazette.com/multimedia/photos/news/take-the-quiz-how-would-you-fare-on-the-citizenship/collection_2a50a5b7-8e34-5401-8e9d-e159f032ac04.html

Thanks very much!
