That's because I am confused on what I am asking for myself, but I can't figure it out until I have discussions about it.

I will say the search page feels incredibly disjointed though; I think it should group all the same content (communities, posts, comments) instead of whatever it does right now.

This is one thing. Another is a being able to possibly toggle views of different instances within one UI. Another is something like multireddits, where you can view multiple communities contents together (/r/funny from one instance, and another).

It sounds to me like you’re asking for some sort of discoverability/content recommendations, perhaps? If this is the case, the general Fediverse culture tends to be against this sort of stuff as they see them as systems that promote more screen time and unhealthy habits, instead of actually engaging with what you know you want to engage with.

Thats a reasonable concern. The problem however I see is that if you don't have way to easily discover communities, or have a way in which communities link to each other, then you end up with a single or perhaps couple massive instances and were essentially back to where we started.

Back in the day, the single entry point of discoverability used to be Google. You'd search for some topic and come onto some forum of that topic. That's no longer really an option. If every instance is isolated on its own domain with no gateway between them, I don't see much point to the fediverse.

The biggest problem to starting a new social media alternative has been the critical mass needed. I see the fediverse as a way of solving this problem, as you already have a bunch of users/content which can be shared with new instances.
