There are a ton of survey sites on the interwebs now. I have found most to be a waste of time. There are a couple that I have been a member of for years and I have received payments and product testing opportunities. One such site is SurveySavvy. I just finished a product test for a new diet cola for SurveySavvy. It was fun to try something that's not on the market yet and give your opinion on it.
If you sign up for SurveySavvy or any survey site remember to fill out your profile completely or you may miss some opportunities.
