People post here to hoover up up the 1000s of lurkers / guests who look at the thread (11k+ views etc.)Do we actually get any referral money from referring each other since we are all already signed up? :/
But again, this plays into the importance of building your OWN platform (blog or whatever) to push your affiliate/referral links with more context around them. A blog post about 'the 10 reasons online studies ROCK!" will do far better over the long term than dropping an affiliate link for the moment
