I'm actually quite curious about how he's accomplishing this... my best guess is that he's using the demographic info to redirect each age group to a different URL, e.g. 18-25 goes to pof.com/a/, 26-45 goes to pof.com/b/, and 45+ goes to pof.com/c/.

I was hoping though, that if my users are talking about cars, they get car ads. (or, even better, mesothelioma!)
