Connect to social network via mobile

I recently posted a blog about a new social network on mobile platforms.But instead of creating new social network why not just connect to yourfavorite social network through mobile? This seems to me a better idea..And I found ZKOUT does the same thing. ZKOUT creates a bridge that connects your online and real world social networks. You require a GPS enabled mobile phone to access real time location information.It would be much lighter on the client side i guess.
