I like themed instances and would enjoy them more if the All feed were personalized instead of the same for everyone.

That’s what your subscribed feed is for…

But choosing an instance that fits you best isn’t possible

It doesn’t need to be the best fitting instance possible. It just needs to be an instance that lets you use and interact with the fediverse in a way that works with you. That’s why a lot of people use generalist instances. They’re no ones “best fit”, but they are also less likely to be bad fits for folk…

Some instances are themed, some are generalist. Because multiple communities can exist around the same topic/theme, the user based ultimately ends up in a community hosted on an instance that fits their needs, because if it didn’t, they would simply move elsewhere.

Which ultimately means that if you get instance banned from an instance that hosts a community you want to use, there’s a good chance you weren’t going to last long in that community anyway…
