Having real time interactions gives a very different feel, it's a little like entering a local pub with bustling activity I guess. In my university years I used an anonymous social app called jodel that would show recent posts in your area. And it kinda had this special vibe, everyday around 8am someone would post a weather forecast for the day and people would greet each other and this type of stuff. Having everybody on the same timeline makes interactions different. And you can have real-time conversations too, which makes me less prone to endless scrolling and more proactive in my use of the app
