Arbitron is fucking stupid. I got picked to do one of these last spring, and they stressed how important it was for me to do it, because I'm one of those all important male 18-49 year olds they're looking for. So told them I would. They sent me a gay diary and $4 in crisp new dollar bills. So I filled it out that day, saying I listened to the really good modern rock station (I know that sounds oxymoronic, but KRBZ is a really good station) and NPR. I waited a couple weeks and sent it back.
Two weeks later I get a letter of thanks and four more dollars! So I made eight dollars by artificially inflating ratings! Huzzah.
