This is another interesting iPhone application - it relays the location and distance of people posting new messages on twitter through the iPhone camera.



This app however seems to provide a more useful function; allowing users to find their way to a tube station without asking for directions is tangibly more useful than seeing where people are 'tweeting' from.



This however is my favourite, and seemingly most feasible iPhone application. Allowing flickr information to tag your face to your social networking sites could provide a whole new level of social interaction through networking sites; although privacy may be a concern.
