Yeah. Speaking as someone who ran a rather large fansite about NIN in the 2000s (the entity now basically exists as a Twitter account), you really cannot just "grow organically" on today's internet. I like to tell people I have a marketing allergy. Self-promotion feels gross. The "if you build it, they will come" mantra from Field of Dreams is not applicable to a world where so much more content is being created than can possibly be consumed. But I realize that if I want something that I'm doing to gain any traction at all, I have to get other people talking about it, and that there are pretty well established ways of making that happen.
When the internet was a smaller space occupied primarily by nerdy types, you could make something interesting and by the nature of the medium, a lot of people found it. You thought you really hit it big if you made Slashdot, but getting featured on television took it to a whole different level. (For example: The Dancing Baby) You didn't need to have a face or a personality - your content actually could speak for itself. But even back then, taking those extra steps usually didn't hurt, either.
Now, the internet is full of professionals of all stripes, and that means you're fighting for attention against people or entities who have a budget for marketing and PR. I can take the most beautiful photos in the world and put them on Instagram, but if I'm not actively marketing that account, no one will ever see them. Meanwhile, some dope with a fresh set of credit cards rents a Lamborghini for a photo shoot, buys batches of followers, and that will grow a following, and maybe he'll get a free night at a posh hotel out of it.
Maybe Bloomin' just does it for the love of it. Maybe Markipler has been able to quit their job and make YouTube their profession. I bet both of them wish they had aspects of the other's experiences. As much exposure as I got to being a small-beans niche internet 'celebrity' (like, on the level of local weatherman), I wouldn't wish fame on my worst enemy.
