NEWS4JAX - Nov 20 - "Singles Around Me" says ~20K singles are installing the app each week. "OKCupid" says one million of its 3M users use the GPS features. And "How About We" estimates that about one in four of its online daters are now incorporating location-based dating into their search for a soul mate. "One of the biggest problems with GPS dating is the immediacy of it," said Alan Rosenthal, author of the book "Safer Online Dating."
