I mostly fit that description. While I understand what you're saying, we all have other interests on top of this. That's what makes it diverse.
Personally, I feel like a more mature audience is needed. I have never liked the feel of places like Facebook, tiktok, etc. Let me have one place where I can pretend the world isn't overrun with stupidity. There is actual conversation on topics to be had, and people aren't jerks to others for no reason.
The fediverse is somewhat complicated to understand. Maybe like usenet or other such places.
