In predicting the future of Twitter, it helps to put it into context with its predecessors in the social networking landscape.
Friendster arrived on the scene in 2003, and it quickly became a popular site for the younger crowd that, which immediately saw the benefit of hooking up with friends, family, and acquaintances online, and sharing communications, photos, and the like. Unfortunately, almost immediately after the launch of Friendster, a group of employees at a company called eUniverse saw the potential, launched MySpace, and within a short span of time were able to convert all of Friendster's users and a few million more onto their own social media platform. By June 2006, MySpace was the leading social networking site in the U.S. Fast forward a couple years, and Facebook has done the same thing -- only in a shorter period of time.
