• Facebook’s Plan To Automatically Share Your Data With Sites You Never Signed Up For – In anticipation of a slew of new features that will be launching at f8, today Facebook announced that it was once again making changes to its privacy policy (you can see our post outlining these changes here).

But while such a plan indicates a tussle with fellow upstart Twitter, the real battle is Facebook vs. Google.
