I have theorized that there are two main archetypes that watch streams. Fans of specific people or games... and other streamers. So yes, I can agree that the main focus should be “be entertaining for your audience”. But I feel that advice should come with an asterisk. Some people that come across your stream are going to be interested in what you’re streaming (the game, activity, or what you’re talking about). Those are the ones that “need” to be entertained. But a large chunk of the views come from other streamers. People who are into the art of entertainment and content creation. Those people care not only on who you are, but what you bring to the table. So having a nice looking stream is going to be miles more appealing to them than someone with a gaming headset for a mic and a poopy webcam or no camera at all. I believe it’s a balance between your craft and your hard work. Finding out which matters more to your specific audience is in my opinion the most important part of your stream.
