At the huge Facebook overhaul event in Palo Alto today, Facebook CEO Mark Zuckerberg unveiled a feature that allows users data portability (Hallelujah). One thing that Zuckerberg kept emphasizing during this talk was that although it’s been a key focus over the past couple of years, Facebook Connect is now one of the two pronged ways that people can use Facebook to leave a footprint on the web. He also kept repeating the key stat that it is now being used on over one million websites.
