Social Media Week (SMW) has taken on the theme for the 2012 conference of “Empowering Change Through Collaboration”.

The worldwide event will look at how social media affects and is affected by global events including weather, political change, etc. The following promo video was released last year, but bears a review here on the first day of the conference.

If you want to follow along on all the goings-on at the conference in any location around the world, see my earlier post about how to follow them on Twitter, via blogs, etc.
