I ran a similar quiz-site for a while before flipping it a couple of years ago. It had heavy integration with facebook, and well was rather spammy (I know I might go to hell).

I just visited your website, I was wondering whether you manually create all the quizzes, or whether you have started outsourcing it seeing that you have been at it since the beginning of time?

Also, I am assuming that all your revenue at this point is from the ads on the website?

Kudos to both of you!

Thanks! I write them all myself, but I use a lot self-written software at this point to streamline the writing process. And yes, 100% ad based. Adsense actually probably pays us the most we could get for our traffic with the least amount of intrusion.
