I think you might have had more luck with clickthroughs if you had posted a higher debt amount. $2000 is nothing, at least in the US. Between just student loans and my car loan I've got over 10x that amount of debt, and I have a smaller amount of student loans than the average nowadays (and many times less than several people I know, some of which have over $100k in student debt...with a humanities degree, even).
So anyway, when I saw that amount I was just like "Ha, that's nothing. My number is much higher." And I didn't feel that compelled to help. I don't really want to admit that, but I thought you should be aware of it, since it's your experiment.
