Google has announced the preview release of Google Friend Connect at Campfire One, which lets site owners include OpenSocial apps made by a world of developers, so visitors will easily be able to join with their AOL, Google, OpenID, and Yahoo! credentials. You’ll be able to see, invite, and interact with new friends or, using secure authorization APIs, with existing friends from social sites on the web like Facebook, Google Talk, hi5, LinkedIn, orkut, Plaxo, and others. And quite simply, you’ll be able to do things together.
If you run a website and would like to add social features, you can now sign up for the wait list and learn more by visiting www.google.com/friendconnect.
