Hey I'm new here still, but it's the same game with every site of this nature. You interact, ask questions, talk to others etc. Here it's especially easy because of the global feed and posts. It's really easy to interact and get seen by others when you post as well, also because it's not a 400000 posts per second thing here like on big (social -)platforms. It's rather chill. But I wouldn't really focus that much on getting "famous". That's more of a big social media mainstream thing. Just have fun and be active. People will know you over time :)
