With the launch of OpenSocial support, members of the over 500,000 social networks on Ning will now be able to add Shopit ecommerce store application directly to their profiles with a single click from the OpenSocial application directory available on every social network on Ning.

Shopit platform easily enables fully functional and synchronized commerce within Social Communities. Users can build stores within profiles with the click of a button and sell to friends, people in their social community, and even people in other networks. Shopit plans to allow controlled commerce functionality, so that Ning social network users can buy and sell across multiple networks in Ning and OpenSocial or simply within their own communities.

“We’re thrilled to provide application developers the opportunity to build and share their OpenSocial applications across the hundreds of thousands of social networks on Ning,” said Gina Bianchini, CEO and co-founder, Ning.

“OpenSocial’s common infrastructure empowers sellers on the Shopit Platform to access more than 350 million worldwide customers within the open source community,” said Matt Hill, CEO of Shopit.

OpenSocial is a community initiative that provides a set of common application programming interfaces (APIs) for building social applications. Ning currently supports OpenSocial v0.7 across all of its 500,000 social networks. Ning’s OpenSocial implementation took advantage of OpenSocial’s easy extensibility to be the first implementer of skins, allowing developers to seamlessly integrate the look and feel of social apps within Ning’s social networks.

Shopit is the leader in free social commerce, allowing users to buy and sell products and services within social networks like MySpace, Facebook, AIM, Bebo, Friendster, Blogger, Hi5, Ning and many more for free.
