Tinder on Thursday announced the launch of Tinder Social, a new platform that helps users plan group nights out. The new platform will help users plan double dates or larger group events, creating new opportunities for people to make connections, the company said. Tinder took the platform for a test drive in Australia and found that users wanted a better way to add friends to their night out in real time. That led to a feature that lets users see who else in the Tinder community is headed out the same night.
