Fun but informational Line Groups, youtube channels, etc

I know there are line groups and youtube channels out there that are fun and informative. I would like to find some and I’m sure I’m not the only one

Great idea to list all the informational online media platforms in one thread. I am curious about Line Groups. Here my favorite youtube channel, it’s probably very known among us.
