So for the first line, there were 140 people that got the quiz right and were eligible to post but only 9 people posted. 150 got it wrong and weren't eligible. Are they unique posters or could have you multiple attempts until you'd cracked it?
Anyway it just seems to prove that no matter what question you ask, very few actually care enough to post. Which seems to me to imply that the quiz is way more popular than the article. In fact, they'd be best off stop posting stuff nobody cares about and move into the quizzing market where they appear to have quite the audience. Could even be money in it.
