Technology facilitates two-way communication in social media through platforms that allow users to interact directly with each other and with brands. Features such as comments, direct messaging, and live chats enable real-time engagement and feedback. This interactivity fosters community building and enhances user relationships, as followers can voice opinions, ask questions, and participate in discussions. Furthermore, the ability to share content easily promotes user-generated content and amplifies brand visibility, making social media a critical tool for marketing and customer engagement in today's digital landscape.
