This is something we started talking about towards the end of last year. For me personally I'd love to set up a second channel for the full Q&A VODs and long-form things, and be able to focus on more bespoke, short-form content on the main channel (including just offering more cool behind-the-scenes looks on YouTube generally). The Q&A VODs are still valuable for people looking to catch-up (since a lot of US people can't tune in live) where Twitch VODs aren't quite as user friendly as YT uploads (in my experience at least!)
Nothing specifically in the works yet because there's a lot to get in place content-wise for 2023, but if anybody happens across this thread and might have any loose thoughts about our YouTube channel in general then I'd be keen to see some of them!
