Mobile social networking, meaning virtual networks bringing people physically together, will inevitably be a pervasive application

Michael Arrington on Techcrunch has just written an article titled I Saw the Future of Social Networking the Other Day, referring to an unnamed start-up that has a mobile social network that runs on iPhone. Arrington writes:

A few years from now we’ll use our mobile devices to help us remember details of people we know, but not well. And it will help us meet new people for dating, business and friendship. Imagine walking into a meeting, classroom, party, bar, subway station, airplane, etc. and seeing profile information about other people in the area, depending on privacy settings. Picture, name, dating status, resume information, etc. The information that is available would be relevant to the setting - quick LinkedIn-type information for a business meeting v. Facebook dating status for a bar.

None of this is new. I wrote about proximity dating in my 2002 book Living Networks and on this blog in early 2003, at the time referring to Imahima, an early player in this space in Japan. In 2005 I wrote about the next phase of mobile social network players including Dodgeball (bought by Google, who did nothing with them) and Meetro, and over the last couple of years I was interviewed on mobile social networking by a number of publications, including one piece in 2006 on What accelerates - and slows - the development of social networking mobile platforms.
