The overwhelming impression that comes across is that the success of this site is just a sign of the times. As SunsetStarLola puts it, "Personally I think the stigma attached to speaking to strangers on the internet has come a long way. Initially it was deemed as totally unsafe and all 'weirdos' but that's totally turned around. I believe people feel more at ease exploring their sexual fantasies with strangers, especially if it's one they don't necessarily deem the norm."
I used to have fun doing surveys while I watched TV. I was choosy about the companies I used and I never paid to sign up for any. I got about $25 in free BlockBuster movie coupons, cashed out about $25 from another site and did an in house project trial where a company sent me to full size body lotions to use and record information about. I had fun, felt like my input was improving the business world, but I wasn’t looking to get rich quick, just earn a little bit in time that typically wasted. Some survey companies pay very little, others pay better. Of course, it is not fair to the businesses conducting the research to lie in order to qualify for a survey and they certainly deserve honest and thoughtful answers to their questions. The companies I worked with told me how much the survey would pay and how long it would it would take. Research for the reputable companies.
