There is a streaming platform out there, focused on games, called twitch.tv. I am streaming my favourite game there ( League of Legends if someone cares) , but it isn't that exciting when not many people are watching. I try to interact as much with my viewers as possible and talk to them and answer immediately. I also have a Facebook and Twitter link I advertise from time to time, but unfortunately it takes pretty long to get a larger community that follows, views and wants to interact in some kind of way with my chat. How can I get a bigger community and hold it eventually?

I know that the viewer/follower count is as well based on my stream quality but I think one can raise the count based on advertisement or a proper engagement with the community as well.
