Ever considered doing your commentary live? Sometimes the best reactions/moments come from when you are live commentating! That's usually what I like to stick to, i actually only do post-comm when doing update videos, and usually then I just talk about recent events that matter to me, let subscribers know of new and upcoming series, make some goals, etc. Eventually you just kind of get into a groove for talking to yourself xD Just do whatever, and always ask for feedback, you don't always have to follow these feedback, but subscribers usually like it if you include their thoughts/ideas bla,bla,bla. Just have fun with it, you don't have to sound more enthusiastic if you don't want...Just, go with it. Thats my view on it anyways, I may not have very many views/subscribers, etc. But im just doing it as a hobby, and I'm having fun
