Show HN: 99folks – an app with a new way to network using geolocation (99folks.com)

How is this different from Sonar?

Business cards can be hard to beat.

I am trying to understand the usecase. Exchanging contact deets, is that the only one?

Hi,the 99folks is an app to share contacts info like emails, phone numbers and social profiles with people geographically near through gps coordinates, it's like a Bluetooth list but you share only contacts info not files, and works using gps and internet, not bluetooth.
