Dan Barker’s been poking at the tracking javascript on Buzzfeed, and found some very interesting data being captured from quizzes:

In other words, if I had access to the BuzzFeed Google Analytics data, I could query data for people who got to the end of the quiz & indicated – by not checking that particular answer – that they have had an eating disorder. Or that they have tried to change their gender.

Online quizzes: just a bit of harmless fun, right? Right?
