Searching/surfing YouTube is like searching/surfing Imgur. It’s a site for content hosting so you can link from other places. You have to go to online communities to find links to good videos.
There are good channels that are worth subscribing to, but going to YouTube directly is like trudging though a swamp.

Good fun game, but online communities are committing to min/max the fun out out of it. I like blowing up monsters, I don’t care about optimising my chaos-per-hour rate.
