Virgin Mobile is launching an array of social networking portals, targeting specific communities and interest, over its mobile Internet service using technology from Intercasting.

While Virgin may not have deals for the massive social networking portals MySpace and Facebook, the Intercasting engine opens up a menu of smaller portals such as Vox and Rabble, interest-specific sites such as online journal portal Xanga.com and LiveJournal and niche social networking portals like AsianAvenue.com, BlackPlanet.com, gay and lesbian site Glee.com and Hispanic community MiGente.com.

The service runs on Intercasting’s Anthem platform, which provides a web-like interface that allows social networking portals to quickly build a portal on the mobile phone.
