Google, whose Orkut social network has tens of millions of users in Brazil, tried to reach further into social networking with the November unveiling of a consortium called OpenSocial, which lets developers write applications for use on multiple social networks. News Corp.'s MySpace has joined, but Facebook hasn't. It quickly objected, citing privacy concerns. Normally dealing with other companies one on one, Facebook can block a service it feels violates its rules. With Google as the intermediary, Facebook lost that leverage, so it decided to block Friend Connect entirely.In a blog posting, Facebook developer Charlie Cheever said Google's Friend Connect "redistributes user information from Facebook to other developers without users' knowledge, which doesn't respect the privacy standards our users have come to expect."
Google responded, acknowledging it passes along data. But it said sharing is limited to links for profile photos of users and friends who have expressly consented to sharing with that particular site. The user's name and numeric ID on Facebook are replaced with Google's own identifiers, Google said in a company blog post.
Google also said it purges Facebook data from its systems every 30 minutes, more frequently than the 24 hours required by Facebook.
Facebook has run into privacy challenges before, most recently when it unveiled a marketing tool called "Beacon" that tracked purchases Facebook members made on other Web sites and sent alerts to their Facebook friends about the transactions.Facebook have announced that they are going to license their APIs and proprietary markup language to other social web sites - the first of which is Bebo. At their own launch announcement yesterday, Bebo CEO Michael Birch said that the company has chosen to license FB’s platform as they didn’t want to add to a format war. In time the company will also add support for “Open Social”.
