Charles Hendricks gave a presentation on using social media for networking and business. He discussed how social media is about building relationships, not making direct sales. He advised attendees to engage with others by sharing content, exposing their personality, and establishing themselves as experts in order to build trust and connections over time. Hendricks emphasized that the goal of social media is developing relationships, not quick commercial transactions, and real ROI comes from the trust built through ongoing engagement on platforms like Facebook, Twitter, and LinkedIn.
