Of the top 10 posts currently on my front page, 2 are about the Fediverse, 1 is about Kbin specifically, and the other 7 are completely different topics including politics, space, video games and art.
Is this on /all? I did see some non-fediverse posts there, but like... a few of them were specifically from @196, which... the name of that magazine is an obscure reference to an inside joke from reddit, and the content is basically just, what if there was a second @memes. It's not pulling people in.
I did see one cool post about Persian Rugs, though, I liked that.
Maybe you should look for magazines/communities other than /m/fediverse if you want to talk about things other than the fediverse.
I've spent a lot of time there, scrolling through them and searching for the ones I want. And it's not that the ones I want don't exist, but nobody posts or comments there. I posted to some of them, but there's no conversation to be had. I commented where I could, but I'm afraid half of those people signed in for a day and then left when nothing was happening.
