Well it's a valid explanation for why Youtubers who DO educate themselves don't rise to the top. The current brand of popular vlogger has maybe three days to a week to finish all his research, so let's suppose you wanted to do a video about the fall of animation.
Well, there are a lot of places you need to look to get the full picture, especially depending on how far back you go. Like in the early days, animation was all there was thanks to Flash being light on bandwidth. But there wasn't just Newgrounds, there were more websites available overall because Facebook, Amazon, Netflix, and Google hadn't gobbled up the internet yet. Newgrounds might be your epicenter, but consider Homstarrunner, Keenspot, Super Heavy, and all the other now defunct companies and websites that you used to go to for entertainment.
I bet if you're too much younger than me, you don't even recognize names like "Super Heavy", so somebody like Quinton has to start from an even harder point where he's got to ask someone who actually knows that old scene where to start.
You've got to do all this in three days.
Never going to happen. Never does happen.
