Hi! I have been a member of mysurvey.com for the last few years, and they are a reputable company that doesn't exploit you, your name, or your information. They send you surveys to complete, and depending on your a/s/l/job/marital status, etc. for 'completion points' that you can redeem for cash and other options. It's not much, but they will also send you samples of new products to use in exchange for a survey. I like it because it only takes a few minutes, and they will email you when a survey is available. I think that the sooner you respond to their surveys, the more surveys they are likely to send you, at least from my experience.
Don't think of it as a source of income - but an easy way to make a few extra $$ w/o doing a thing but clicking on a few answers!
