I use YouTube a LOT, both as a content consumer and content creator.
I create content on two different channels, my online biz channel and my games/non-biz channel.
As for content consumption, I mainly watch current affairs, history, crypto, online biz and self development stuff... also chess vids, boardgame rules vids, wargaming vids, oh and some comedy and crazy short vids too 🤣. Blimey, seems like am an addict!
