Quiz Services

I’ve been thinking about creating a big quiz on post-apocalyptic fiction, for fun, and to help promote Wastelands, but I’m torn on which quiz/test service to use. Anyone have any recommendations and/or opinions on which is the best? I’ve done a number of tests on OK Cupid, though that’s a dating site, so that seems like a bad choice for this endeavor. I thought about doing something on Facebook, but the only quiz generator I saw was related to Flixster (which is for movies, though it seems to let you create quizzes about other subjects).
