Oh those young persons! How they love their social networks. New research results indicate that millenials (those born between 1981 and 2000) are also eager to embrace mobile Web 2.0 technologies, which include cell phone-based blogging, multimedia sharing, location-based socialization services, gaming and chat.The report released by market research firm In-Stat revealed that five major types of mobile social networks dominate the landscape in these young persons' lives: * SMS messaging networks * Friend/community networks * Personal content networks (photos and blogging) * Location-based social networks * Dating networksProjected to jump from 525 million users this year to 975 million in 2012, the number of global mobile social network users will certainly impact advertising revenue, but not as much as you might think. In-Stat says social networking has been rather ineffective at gathering the appropriate metrics to gauge the impact of ad campaigns and the advertisements run on social networking sites. But the potential is there. And with existing mobile-specific social networking sites, like ZYB, MocoSpace and Mig 33 springing up, they are sure to be hard at work to harness the propensity for revenue. These sites are eager to follow in the foot steps of Facebook, who leads the social network charge and has also offered a mobile application for popular smart phones like the iPhone and BlackBerry. It's a global mobile world indeed! The largest markets for Mobile Web 2.0 are in the Far East and China, Western Europe and North America. Yet, it is expected that in the coming years India, South America, Africa and the Middle East, Eastern Europe and the remaining parts of Asia, will show significant growth as well. Young people will certainly dictate the path that global mobile social networking takes. It's not only important to note the impact that such mobile technologies will have on the rest of us, but also to note the impact that a generation will have on technology.
