There is a huge difference. When we interact in person, we are building a mutual relationship. Your friend may tell you about their new job, but may chose to adjust the tone and information to be more sensitive to the layoff you just experienced. Online, you get unidirectional bragging that needs to be as engaging and exaggerated as possible to get promoted by the algorithm. Their new job becomes the pinnacle of a lifetime of stellar achievement. If people interacted in person like they do on social media, the rest of us would avoid them like a contagious rash.
