Social translucence is like when you can see what everyone is doing. It's like when you're in a busy place, like a store or a school, and you can see what everyone is doing and everyone can see what you're doing. Social translucence lets us know what everyone is up to and helps us to understand what is going on around us. It's kind of like when you look out a window and can see what's happening outside - it's like that, but with people and things they're doing.
