I feel that Twitch chat greatly enhances the viewing experience, and if it was changed or removed I would have no reason to watch something on twitch compared to any other platform. Take for example the Bob Ross marathon. Without chat I could have just watched that on Youtube or Netflix, but chat is what made that special. 50,000 people watching together, seeing the memes evolve as the stream went on, hello bob, RUINED, SAVED, goodbye. I don't think its pointless or annoying and the fact it feels like going to a concert is the best part!
