@tomw @cammac as an aside, Twitch chat is IRC, you can use an IRC client to connect to it, and some of the people I know from back in the day do.

I use an app called Chatterino that is a multichannel chat client that makes use of that fact, so when I'm on a channel that is co-streaming with others I can see/interact-with the chat from them all while just watching one video feed.
