Most of my viewing experience is with retro game speedrunning and the specific advice for that community is to pick a game you want to learn and follow the best players. The world record holders and their friends tend to be very happy to share advice and tips for their game with new runners. This is great because it helps you establish a relationship with them without being “that guy” who is just there to try and promote his streaming channel (those people are universally reviled and often banned for unsolicited promotion). Instead, if you’re a legitimate member of the community, learning and improving at the game, then the big streamers may be happy to send you a raid.

It’s very much not a get rich quick scheme. It’s more like moving to a small town. You need to put yourself out there and ingratiate yourself to the community in order to gain trust and become a respected member. The above advice should be largely adaptable to any form of streaming with an established community.
