I struggle to watch the streams myself. I get distracted prepping my own games. I do really. Recommend Harmonquest though but that's more to do with them getting a cartoonist to draw every game.

It's going to be a huge medium for the new generation though. Kids today are watching YouTube in place of TV. My daughter loves watching this ditzy teenager opening toys and play with them. I don't get it but it's absolutely a thing now.
I'm in the same camp that the videos are tools first for education. Still much prefer to watch a movie and rely on YouTube for mapping tutorials etc.
