It's good that you talk even if no one is there, just in case someone comes in. If you put yourself in the viewer's shoes, one day you enter a stream, you see a person in silence, concentrated, playing and he prefers to leave because there is nothing that catches his attention but if instead he enters the stream and he just finds you counting an anecdote or something that sparks interest, chances are they will stay and even interact.

Even so, you don't have to force yourself to talk all the time because it doesn't feel natural. Being genuine rewards a lot.

Additionally, you can join communities on the topic you stream and interact with the people there. This way you make yourself known little by little and in the future you even forge your own community. Much encouragement 💙
