Social media is changing the way our public discourse is conducted, says Deanna Zandt, GRITtv's very own TechGrrl and now the author of a book about social media, Share This! By changing the way we interact with media (instead of passively consume it), social technologies from Twitter to Facebook are injecting our personal lives and values into the public space and forcing the doors wide open for potential change.

According to Mashable.com it's Social Media Day today, June 30, and so who better to join us in studio than Deanna Zandt, along with author, radio host and social media expert Farai Chideya. They discuss participatory media, privacy concerns, the iPad, Net Neutrality and more.
