Because I believe in inclusiveness and I champion uniqueness. I don't even want to be a pseudo-celebrity. I just want to make intriguing content. Whether or not I'm personally recognized for it is inconsequential. If my channel gets popular and no one at a convention recognizes me, that would be great.
I mean no offense to the many Youtubers that fit that description in some sort of reverse-racism spiel, but I get bored of them. Every "reaction video" or the like has the same looking stereotype on the same looking thumbnail. If I'm going to create content for a living, I want to be different. Somehow. I just don't know how.
You be different by being you, and bringing your unique personality, creativity, and viewpoint to the table. Reaction videos are generally same-y because they're mostly trying to cash in on a cheap style of video, regardless of if their heart is in it or not, and regardless of whether or not they have an interesting personality.
As opposed to Maximilian, whose reaction videos are entertaining because they're heartfelt and he has a great personality.
Similarly, one of my favorite YouTubers is Ross Scott, creator of Freeman's Mind and Ross's Game Dungeon. His latter show is fairly plain on paper--just reviews and analyses of various games he wants to talk about. Many of them can be over 40 minutes long, too, making them not exactly an easy watch. The appeal of his content comes from two things: 1) the games he chooses, which are all often old and obscure, so his content becomes a little intriguing and informative that way, and 2) his personality and sense of humor. He's not the "make excrement and sex jokes nonstop" brand of humor--those things virtually never come out of his mouth. As such, he has such a unique brand of humor and presentation that
he can manage to make a 42 minute long video about an obscure Polish PC game from 2007, and it'll get over 400,000 views.
So, apply the same principles to your work, and it'll rub off on people. If you have an interesting personality and present it well, people will take to it.
Visual distinction is important, but not in the way you're thinking of. The color of your skin shouldn't matter as much as your words and character. But really, if you're making an analysis video, what's going to matter is if your visuals are engaging. I haven't really watched Sequelitis because I find Arin's arguments to be deeply flawed, but he presents it in a unique way with his animation, and that's part of why those videos draw so much attention; they're visually interesting, even if what he's saying is crap.
Game Theory understands this as well. They have a distinct visual style that presents the content of their analysis in an engaging and creative way. So for all their flaws, GT does get presentation right. They don't just play clip after clip of footage to get their point across, but instead have different visual representations of what they're communicating.
I say all this as someone who's been out of the content creation game for a while, and whose most popular video had neither of these two principles, so take it with a grain of salt. But this is just one of the things I contemplate despite not having participated in a long time.
