Like Lemmy or any social media really, you get out what you put in. If you just follow the generic feed without following anyone, yeah it’s going to suck.
You can make lists, so one for your friends, one for news, one for a hobby. Or you can filter hash tags to really narrow in on a topic. People also make “starter packs” of who to follow for any topic you can think of.
This format is also unbeatable for breaking events.
Ignoring lint issues comes to mind as an at least somewhat reasonable use case.
