SixQuestions has increased its referral bonus — you used to be able to earn 500 points for referring a friend; now it’s up to 1,500! They have also added $10 GCs in the redemption area (used to be the cheapest ones were for $20). They’ve added a lot of big-point offers that don’t require a credit card, too. I think that actually taking quizzes is the SLOWEST way to earn points there now! Anyway, if you haven’t joined and want to give it a whirl, please join here — thanks!
