San Francisco-based social networking startup Hi5 has just raised a hefty $20 million in its latest round of funding.

Now touting some 30 million members, GigaOM notes the social network's unusual history.

Hi5 began life as matrimonial site with social features targeting the Indian diaspora, then morphed into a social network, garnering a following in some Latin American countries, as well as Mongolia, Tunisia and Romania.
