That's Facebook. ;)
But okay.. if we assume that many people only have time and energy for one main social network, could you briefly tell me what your site offers that other networks don't (especially FB)?
Jamafriend is a social networking application that displays your location and your friends' location on the Google map with links to current weather, headline news and current events as long as valid locations were provided. To protect people's privacy, Jamafriend doesn't automatically geolocate your location. It's up to you if you want to provide your location and manually enter it on our system. Another thing is you can choose a design for your photo album and can change it anytime.
And not familiar with Facebook's TOS, so maybe this isn't even possible, but would it make any sense to investigate taking your innovations and developing a FB App or integrating with Foursquare's API somehow?
Not trying to rain on anyone's parade, either. :)
