You can get a lot of people VERY intruiged in your content if they know you have a stutter. People are utterly fascinated by speech impediments, and if you confidently go forward with this and openly stutter in front of everyone on stream, they will stay and be interested. And better yet, if your content is actually good, it's a recipe for strong appeal. NO doubt you will have people teasing you but if you expose yourself to the entire internet, of course they will show up now and then. But you will also have the ability to build a really strong audience that will always want to come back and hear you speak, and see how your life is like streaming. You might get a lot of questions and confusion but it's also a great opportunity to teach everyone about stuttering. I've actually always wanted there to be a big streamer with a stutter, because how cool would that be for us?
