NEW YORK TIMES - Mar 26 - Grindr, which claims to have 3.3M daily users, will send men who opt into the service a reminder every three to six months, and simultaneously point them to the nearest testing site. It will also let clinics, gay community centers and other testing sites advertise for free. "More than 107k gay and bisexual men in this country have H.I.V. but don't know it", said Dr. Jonathan Mermin, chief of AIDS and sexually transmitted diseases at the Centers for Disease Control and Prevention. "And there is typically a three-year gap between the day they get infected and the day they find out."
