Why do you use YouTube?

YouTube is my primary source of entertainment but also secondary source of knowledge. For something complicated i have no knowledge about (like how to correctly fold a suit lol) i like to watch a YouTube video tutorial. For everything else i mostly just search on Google. But i'm also subscribed to some tech channels like LinusTechTips or a german Security and Tech channel called SemperVideo so i know about the latest most important gaming and consumer security stuff without having a news ticker.
