I take it there's no criteria for what to share, just 'good channels?' Okay, I have a guy who hopefully blows up more soon, because he's one of the best channels I've run across in years.
Night MindHe reviews/deciphers/chronicles the many creepy mysteries of the internet. Anything from obscure Alternate Reality Games to well-known things like Don't Hug Me I'm Scared. If it's creepy and online, he's there. Even if you've already seen a video breakdown of something he's covered, his breakdowns tend to be more thorough and convincing.
I know a lot of people don't like his voice, but I love it. It's soothing.
