You can browse by “local” and “all” with the tab at the top of the page. Local is posts from just your instance, all is everything not defederated with your instance.

That’s why I suggest people go to a instance with as few deferations as possible. You can block instances, communities, and users. You know what you want to see. You don’t need a admin to tell you what you want to see.

I’m glad instances with tons of defederations exist for those who want that, but that’s not for me.
