Now, the interesting part: Google would pay you for the surveys you participate in. According to FAQ they’ll pay about $75 per hour:
Do I get paid?
Yes – it depends on the type of study, but typically we pay $75 for each hour that you spend with a Google researcher, either in person or on the phone. Most studies last for one to one-and-a-half hours. We don’t pay for your travel time, or travel expenses, though. For online surveys, which you complete from your own computer, the amount varies, depending on the length of the survey.
It is well known that Google’s main policy is “Do no evil”. And now they are also moving a step further and trying to adopt changes as per user feed backs. Google Rocks! 🙂
