Following a hashtag will show you posts with that hashtag that have made their way to your instance (server). Posts usually get to your instance because someone on your instance is following the poster, which can be an issue for smaller instances. (There are things called relay servers to help with that, not all small instances make use of them.)

In addition to following hashtags, you might want to seek out something like fedigroups. You can find info at https://about.fedigroups.social/home
