[shibboleth]

The majority of survey takers do so for personal monetary gain, not for charity. That's why practically all survey sites give points which can be converted into cash and gift cards. Now I'm not saying that eval.me will be unable to find users and companies to use its service (I'm positive it will), but my guess is that it will pale in comparison to traditional survey operations. But I do hope that I'm wrong and that eval.me becomes a great success.
