Designed to help Web publishers easily add social-networking features to their sites, Friend Connect requires just a snippet of code to bring social features to a site along with a means of coordinating them with other social networks like Facebook, Plaxo and Google’s Orkut. It’s another in a recent string of data-portability efforts that hope to apply the distributed model to social networking and put an end to its so-called “walled gardens.”

“The distributed model has worked well for the Web,” David Glazer, Google director of engineering, told Outside the Lines’ Dan Farber. “That is what the Web does–many points of light loosely coupled and massively distributed, allowing users to connect to pages of information. Now it is working to connect people to other people.”

And all of them to Google AdWords, of course. More Internet usage. More ad revenue.
