You’ve been invited to share your expertise and passion with a live audience. Congratulations! Every time you present — whether it’s to a dozen people, or a thousand — social media gives you the opportunity to better engage your in-person audience and effectively reach people around the world [beyond just your “live” audience] who are interested in your topic.
Thank you for your question. At the risk of hyperbole, it is impossible to overstate the importance of social media in magnifying both the reach and the impact of your content, regardless of whether it is a formal presentation or your regular blog post (like this one!).
