Maybe I just don't find the right people. On Twitter, I can look up people I'm interested in. Like "That company is doing something cool, let's follow the CEO on Twitter". But on Mastodon?
Is there anybody 'normal' on there who posts substantial stuff?
Most likely don't want to leave for other networks because what they have works for them. An alternative to the mainstream doesn't appeal to people who don't reject the mainstream, and another social network alongside what they have might seem redundant.
But if you think people are divided up into “normal” and “not normal” (and your definition of normal is “some CEO”) then yeah, maybe Mastodon isn’t right for you.

As another poster put it "An alternative to the mainstream doesn't appeal to people who don't reject the mainstream".
I think what you're trying to say is "the aforementioned social network doesn't have people who share the same interests as me" rather than it being full of people who are mentally unwell.
