No other form of communication enhances, adds too, or improves on these things - with the possible exception of VRChat.
Voice chat and message chat offer a fraction of the full experience. Not to mention dealing with unreliable and sketchy brokers and middle men. You can talk, but there are rules, sometimes subscriptions, or other strings attached. Also they get to spy on you and sell your private information at will. Social media is lesser still. A feed about your life so acquaintances and strangers alike can casually browse your life history at will. They'll know about you, but never really know you. They'll only know what you show them.
You see, it's not just about the richness of information or experience for its own sake. Ask yourself why we socialize? What's the goal? It's to develop a connection. But there's a difference between good and great connections. How strong of a relationship can one develop when the "handshake" is limited, restricted, and fundamentally flawed?
