My neighbor is a popular streamer and I don't know what to do

So I just recently found out that the popular streamer and youtuber "class roofer" or "exercise roofer" is my neighbor. I've always been a fan of his, and I've been watching him for almost two years now. He just recently got a stream going and I'm planning on giving it a look. But I don't know if I should show my support to him or not. I don't know if he'll like me showing my support to him or if he'll get annoyed by me. I don't know what to do.
