TECH CRUNCH - May 1 - Facebook built Dating to be privacy-safe, hoping to avoid the awkwardness of friends or family checking out users' romance profile. Facebook has announced at its F8 conference that Dating is opening in 14 more countries, bringing the total to 19. It will launch in the US before the end of the year. Dating brings with it a new feature called Secret Crush. Users can choose up to 9 friends they like-like. If they've opted into Facebook Dating, they'll get a notification that some friend has a crush on them. If they add them as a Secret Crush too, they're both notified and can chat on Messenger.
