Depending of your instance, see the local communities, you should have some for “community request” or meta, look for the description of the communities.
You can also request on other instance, doesn’t need to be on your instance. Some can be more restrict then others.
There’s also theme specific instances, like Star Trek, Path of Exile, FOSS… each instance can have his own rules.
I've seen Lemmy contend grow day by day, one month ago I needed to change sorting from active/hot to new posts, s it show posts from today.
Now every time I see posts from less an hour with changing from hot, and more people commenting (and an lot of cat pictures).
I'm where since 2021, and you could visit lemmy after a week and see the same posts, now feels that people is posting more and engaging more.
You don't need to "fight for attention", is you post someone will upvote or comment.
Lemmy stills small compared to other platforms, but more friendly and civilized.
Same but I use Syncthing instead
