Started doing a Nielsen Radio Ratings Diary. Got a pack in the mail from them (they said my house was randomly chosen, but I also completed a breif tv/radio survey a few months ago that was also apparently randomly chosen, they paid I think $4 cash for it total) that came with two diaries for household members. Each diary comes with two dollars cash inside and the actual diary to send back (the postage is all part of the diary so just place the diary in the mail) and then they will send $10. I think it's kind of cool to share input how I listen to radio and also fairly easy since I only listen to one station (WFAN New York) during my morning commutes. There's a comments section, so I think I will voice my opinion about the lack of a modern rock station in NYC.
