Deanna Ferrari gave a presentation to Slippery Rock University students on social media's role in public relations. She discussed how social media has changed PR and provided examples like the "Miracle on the Hudson" and Michael Jackson's death. Ferrari also warned about social media fails and advised engaging audiences, maintaining good communication skills, and using social media as a tool to facilitate relationships rather than just broadcasting messages. She emphasized learning multiple social networks and apps, using them from a business perspective, and having the right skills and tools for success in social media and PR.
