IDK why is everyone making accounts on the 3-4 biggest instances.

How do you expect a newcomer who has no understanding of content federation to find these low-pop instances? Of course everyone's joining the main handful, they don't know anything else exists.

I'd imagine most people coming from typical social media don't even realize that instances are a thing when they sign up on one. They've heard about lemmy or kbin or whatever, so they go to lemmy or kbin or whatever and sign up. Once they learn how it works, they've already established a profile on that instance; they're not going to start over on a new one.
