The trend-watchers predict that mobile phones will become a major computing platform over the next decade or so, equalling or superceding the current capabilities of desk- and lap-tops. If that is the case, social networking will almost certainly be a driving force behind the change – and ‘loopt’ is just the sort of application to do it. ‘Loopt’ is a location-based mobile social mapping service, using geotagging capabilities to keep the user informed of the locations of people in their network relative to their own. You’ll never have to ‘just miss’ someone again – unless you really want to, of course.
