I enjoy smaller Twitch channels where the chat isn't going 1000mph because you can actually chat with other viewers. There's definitely a parasocial element if the streamer reads your message, but it's more that it's an online community with shared references and in-jokes.
Also the people I follow are mostly part-time streamers doing 3-4 hour streams a few nights per week, so they don't need many breaks like the ones doing all-day streams.
