Seriously, stop blaming the network/platform/software/protocol if you are not seeing the content you want to see, or seeing content you don't want to see.
Every #SNS, or #SocialMedia network, is based on (1) who you follow; and (2) who you and the people you follow interact with.
In other words, what you see and don't see was based on your how you're growing your own network. That is your personal "observable network".
It gets worse in platforms with algorithms because they push far more similar content you wouldn't normally see if you don't have any connection path to those (again, who the people you're following are interacting with).
In platforms without an algorithm, like most #Fediverse software, the closest you can get to something similar is your "Instance timeline/feed" and "Fediverse timeline/feed", which are generally 'hidden' behind another tab/section. Not like in, for example, #Threads, "For You" is the default. ("For You" is currently like the "Instance timeline/feed" but with algorithms.)
If you're seeing too much tech mumbo jumbo, you're probably following a couple of tech accounts. Or, maybe, you're just following one techie account but they're far too active in this type of content.
You want to see more art content, you have to find and follow them. Use hashtags and see who else are using it and follow those accounts you like. Or, if you like things being fed to you through an algorithm, you have to keep feeding that algorithm with keywords so it will learn what you want (again, like in Threads).
What you see and don't see is based on how you're growing your network. It's no different from your offline life, you see and hear only the things people that surrounds you are sharing.
It is not the fault of the software/platform/protocol/instance/algorithm (or lack thereof). It's all about #YOU, you are center of your "observable network". Just like how planet Earth is the center of its own "observable universe".
