The recent Pew Survey reports that almost 85% of the Americans own a mobile phone and within the 18-29 age group almost 96% own them. I guess it is not surprising that whether you are at a metro station waiting for a train or crossing the road, you find that people are engaged with their mobile phones. It would be interesting to know, if the increase in mobile phone ownership is also leading to the increase in location based applications such as Foursquare.com and Places in Facebook?
