http://www.google.com/friendconnect/ http://developers.facebook.com/connect.php Where people who have google accounts can use that to log into your own website? Does anyone know?
GFC Has better sign in options. You can log in with a Google Acct, Yahoo Acct, AIM Acct or OpenID. Whereas fb connect, you need an fb account.
