I tried some of those online survey pages, it's a bloody waste of time. You need 5-10 minutes of a very personal question to determine whether you're in the target group for a survey (unpaid). To then go do another 100 very personal question that earns you 1.5$ and payouts are possible 50$+ only. It's just human abuse to create and publish those websites.
I'm still running my survey on Twitter:
97% of the Votes are funneled by a paid promotion and therefore rather unlikely Hivers. Overall only 28.4% of the people don't want to make money posting online - and I don't believe them! Everyone wants to be paid and loved for just spilling the beans all day.
