How trustworthy are these online income sites? Has enyone registered in any of them, worked and earned?

I've used Turbotax for the past few years, they do charge a fee, and take it from the tax return. I am not sure if you owe how they would collect. Usually I get a direct deposit within 2 weeks.

I've used the site www.your2cents.com/ for probably a year now. I have received a check a few times from them.





www.greenfield.com/


is another site I have more recently joined. Though I don't like it as well as the first site and I have not received a check or money from this site yet either.(should be getting one in 1-2 weeks from now)





as for a non-survey money sites like nutang.com and other profit sharing sites. I could not tell you if they work, I have never tried any of them out.
