Social network fatigue? Maybe not on mobile
Analysts, naturally, offer a range of estimates for worldwide use of social nets via mobile devices. At the conservative end, ABI Research says 140 million users by 2013. On the wild side, Pyramid Research says 950 million users -- about one seventh of the world population -- by 2012.
If that holds true, by then it will be so very 20th Century to use a mobile device just to make a lowly phone call.
