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!
