Social Media and Site Selection

I'm recalling a recent stat I heard at the IEDC conference with regards to site selectors and social media.

70% are on LinkedIn
50% are on Facebook
33% are on Twitter

Good to know.  Thanks for that stat from the IEDC conference.  I like it but I can't recall exactly to whom to attribute the stat.  I was alerted that the comment was during a "What Would Google Do?" presentation which means it was either Ben Wright, Anatalio Ubalde or Andy Levine.  Thanks, Ben, Anatalio, or Andy.
