Darwin's Data is a new survey site but instead of getting asked those boring old marketing questions and having to answer a gazillion questions about what kind of toilet paper you buy, they ask you what your opinion is on various legal situations. They'll show you a video showing a legal dispute and ask you questions about it afterwards. Then they'll send you a $25 amazon gift card.
I haven't had a chance to do one of these types of surveys yet but right now they are giving people $10 amazon gift cards for signing up and I did get one of those. So I have no reason to believe they would scam anyone. :) And from what I've been reading online no one seems to have anything bad to say about them.
It's important to note that if you start a survey you have to finish it in one sitting. So if you don't have time to finish it or you think you might be interrupted, wait until you have more time. If you don't complete it in one sitting you won't be able to take it again. According to their site it can take up to an hour to complete a survey.
From what I've been reading online you won't get a lot of surveys but this still sounds like a great way to get some spending cash from time to time. And of course, you can find pretty much anything on amazon.
If you are interested in signing up for Darwin's Data just go to DarwinsData.com and click "request an invite" and you should get an e-mail from them. It might take a little while to get the e-mail so keep an eye out for it and make sure it doesn't accidentally go into your spam folder.
