Friendster is a social network that was founded in 2002, a year before Myspace and two years before Facebook. Consequently, it is often thought of as the grand-daddy of social networks. At its peak, the network had well over 100 million users, many in south east Asia.In July 2009, following some technical problems and a redesign, the site experienced a catastrophic decline in traffic as users fled to other networks such as Facebook. Friendster, as social network, simply curled up and died.
