One of the main things thats important for streamers is really viewer interaction. If you're actively monitoring and talking to the chat, you'll get a lot more a lot faster.

A webcam is pretty much essential because its creates more of a connection between the streamer and the viewer.

You need to keep stable times. That means you come on at the same time every time. Then people will know when you're on and when you're not, it becomes tedious to check it somebody is online constantly, so have set times you stream.

The problem with games like Sc2 and LoL is that they require constant focus and attention, meaning you don't really have to much of a chance to talk to the chat. Diablo 3 is a great game to play, its extremely mainstream at the moment and lets you chat at the same time. The only problem that comes with this is that the d3 streaming market is so inflated right now, there are literally thousands of people streaming it.

As for gathering dedicated followers, you need to have some kind of niche that people only really get when they come to you.

Right now isn't the best time to start because there are so many streamers of d3 and thats pretty much what almost everybody is watching right now, its going to be hard to pull in people when they have so much choice and there are the super popular people streaming. That is why having your own personal niche is so important.

If you're going to stream every day you need to be prepared every day. What I mean by that is, when you're streaming especially with how popular streaming is, you need to be on the ball. If you're not at your best or don't feel like streaming, you have to keep to your hours and keep at it. Even if you're not feeling at your best, you really need to try to remain as awesome as you can.

If you're not a friendly, fun, interactive streamer, you're not going to get anywhere. There are hundreds of streams of just people playing, no interaction, no fun or discussion, nothing. People can just as easily go watch some other guy who's doing the exact same thing as you but he's getting more viewers, because its going to be more lively and our instincts tell us that if one person have more viewers than another he's gonna be doing something better, and go, even if they aren't.

You're doing a bad thing by not linking your channel. To get those initial viewers, you need to have your channel up at places, you need to get publicity. If you don't have people who know you, then they're not going to come and build a firm foundation for more people to watch you.

There's probably loads more stuff I'm not thinking of right now, so feel free to shoot some questions.
