I've been streaming and making youtube clips for a few years now. I'm not famous by any means (62 on Twitch, and 550ish on Youtube). I've never had anyone comment on my stutter, even when in my mind I knew I stuttered like crazy. I've actually had someone who said they also had a stutter, which was really cool. I've never told newcomers, 'Hey be warned, I stutter'. They'll probably figure it out on their own lol. I do use the stutter tag though sometimes. All in all, just do it for you and be sure to have fun.
