The torrent of social media evidence continues to grow and X1 Discovery continues to monitor online legal databases of state and federal court decisions across the United States, where evidence from social networking sites played a significant role. Now, with over 320 published cases in the first half of 2012, not counting de minimis entries (defined as cases with merely cursory or passing mentions of social media) we are sharing the list here for our readers. For more detailed analysis on many of these cases below, please also visit our blog, Next Generation eDiscovery Law & Tech Blog or view our webinar on Social Media Ethics.
