@grimalkina I'd say, regardless of the method of curation you decide works for you, curate your feed. I try to keep mine populated with only stuff I care to read about simply with # filters. I also follow a few people on top of that who have different interests to add in some variety I would likely never see elsewise, such as this post here. This place is full of just as many meaningful back-n-forth conversations as it one-liner garbage you'll forget about an hour later. There's loads more conversations happening that you can chime in on than just what's being presented to you by your instance. Start with simply searching for things that interest you, then figure out how to automatically have your feed show you those things.
It also may help to at least get yourself a taste of what other fediverse platforms have to offer. Your confusion(?) may stem from the fact that Mastodon doesn't give you what you're lookin for here, maybe it's Lemmy, Akkoma, Misskey, Friendica, or something else. While Mastodon does tend to favor a more short-form (Twitter-like) conversation flavor than most of the others, it doesn't explicitly restrict you to that sort of content.
At the end of the day though, if you see the things you're interested in, and you're able to take part in the conversations you want to, you've done it all right enough.
