Don't let anyone ever tell you that your opinion isn't worth anything. In fact, your thoughts are so valuable that Google is willing to pay you for them. Well, there are two caveats - you must live in the US, and you have to be fine with being paid in Google Play credit. But hey, when it comes to Android, that stuff is as good as cash.
Users can spend Google Play credit on digital content in the Play Store, including apps, games, music, books, magazines, and videos. The app comes from Google Consumer Surveys, so expect questions to center around product usage and shopping habits. Surveys might ask your opinions on which logos are the most attractive or which tourist destination appeals to the most to you. A notification will pop up roughly once a week alerting you to presence of a new set of questions. It's nothing too taxing, and it could make for an easy way to pay for that 99 cent app you're dying to have.
Your responses will be anonymous, but you must still provide a Google Wallet account in order to get paid. An initial survey tests whether or not you are eligible to take part in the program, and in typical Google light-hearted fashion, it's not meant to be taken seriously. One of the questions might even give you a sense of déjà vu.
