The New York Times writes:
The social networking phenomenon is leaving the confines of the personal computer. Powerful new mobile devices are allowing people to send round-the-clock updates about their vacations, their moods or their latest haircut.
New online services, with names like Twitter, Radar and Jaiku, hope people will use their ever-present gadget to share (or, inevitably, to overshare) the details of their lives in the same way they have become accustomed to doing on Web sites like MySpace.
Unlike the older networking sites, which are still largely used on PCs, these new phone-oriented services are bringing the burgeoning culture of exhibitionism to more exotic and more personal locations. They are also contributing to the general barrage of white noise and information overload something that even some participants say they feel ambivalent about.
