We've completed the beta test with Cognitive Labs surveys and so now we want to announce its general availablity. In it, you can opine on anything you want, sometimes for free gifts that we arrange through partners.
Our survey and quiz engine will ask you about almost any topic under the sun that affects thinking, and hopefully, will allow us to keep improving the service.
You told us you wanted more tests, so we've added brainpal, a quick reaction time trainer.
What's your favorite vitamin? Maybe you'll tell us. We'll be back later.
