Friendster just deployed OpenSocial, as part of the Friendster Developer Program. OpenSocial applications can now be introduced to over 75 million Friendster users around the world.

This is particularly exciting news to me since, while Friendster is not the first social site that uses PHP Shiding for it’s OpenSocial support, it is the largest by a good margin. This brings the total number of end users using PHP Shindig to some 90 million, and increases the total number of OpenSocial users to at least 365 million; Truly an impressive milestone for all who have worked on the PHP version of Shindig and for the OpenSocial community.

For more information see the announcement on the OpenSocial API Blog, and Friendsters Developers Platform.
