For forget sake, the reason they're so popular is because of YouTube promoting them if they have fame. YouTube used to be a place about sharing videos and getting yourself noticed and now it's just turned into a circle jerk of youtubere who have hardly any talent. Hell, YouTube even treats some of their less popular youtubers like absolute stuff. Example being Bl00dblitz or robs rants. I'm not saying the more popular people are bad, I'm saying YouTube is promoting them. Like those recommended videos they give, it's because they're promoting them because they make the most money off of them. So it's basically an unreadable system where YouTube is the winner either way
Also since when did skydoesminecraft get so popular
