As a customer, after you buy and use a product, you gain valuable knowledge about the product. By sharing the knowledge with other consumers, you help them make a wise purchase decision, and you help businesses sell their products. However, the sharing of product knowledge is traditionally considered as voluntary. In, we want to help you capitalize on your knowledge, and let you earn cash for sharing this knowledge. With social media, that means you can make money by pressing a button. So what are you waiting for? Sign up and start making money!
