Facebook launches Viewpoints to gather user feedback
Facebook is looking to gather feedback from its users in the US with a new market research app. 'Viewpoints' gives people over 18 a financial incentive to share their views on Facebook's suite of products, which includes Facebook (obvs), Instagram, and WhatsApp. The first survey looks at the effects of social media on well-being and, as the company says: "Information from this survey will help us build better products that aim to limit the negative impacts of social media and enhance the benefits."
