Hey Glider,
From what I've learn from streaming and watching successful streamers is that you have to be interactive with your viewers. TALK TO THEM! No one wants to just watch someone sit there silently and playing games.
You should also have ACTIVE & INTERACTIVE mods that will talk to your streamers, answer questions, and moderate the chat (kicking people who are toxic to your chat)
One more thing would be to be CONSISTENT with streaming. Don't be discouraged if your first few days only have 1 - 10~ viewers total, it will grow as your stream more and consistently.
