Is this why a bunch of my FB friends started giving out their pins again? So that this "social experience" can kind of, you know, take off? Cause with WhatsApp I just use my number, hell, it even pulls in all my friends who has WhatsApp already installed... ANYWAY... you guys enjoy sharing your pin numbers with the rest of the world... I guess there motto is "It's hard to code, it should be hard to remember a pin to add your friend too"
