paul, who runs the site, is a great guy and tells it like it is--the good, the bad and the 'completely not worth your time'. he is always digging around and discovering new focus groups and survey companies--and never hesitates to share his finds.
moreover, he actually started a forum on the site that is more community based (think slickdeals or reddit without the egos or intimidation) where people can post their finds, ask questions or list current focus group screeners. the vibe is so inviting, approachable and merciful! i have found and qualified for several studies just from the Cool Work Ideas Forum. definitely worth the bookmark to check for nationwide studies daily.
check it out and may the focus group be with you!
