Google's third Campfire One event Monday night featured the debut of Friend Connect. David Glazer, Google director of engineering, has described Friend Connect as a "salt shaker full of social to sprinkle social features on a site in a matter of hours."

Web masters and developers can sign up to get on the Friend Connect waiting list here.
