Break out the champagne bottles and pop those corks!  As of 11 June 2013, there were 15 million Facebook (FB) users in Vietnam, a penetration rate of 16.39%.  This means that nearly half of all Vietnamese connected to the Internet are “facebooking.” 

Vietnam ranks 17th in the world in FB use between Spain (16th) and Egypt (18th).  In fact, there are more FB users in Vietnam than Malaysia, Taiwan, Japan and South Korea.
