And all the comments are about how hard fedi and mastadon are :(

Skill issue.

I haven’t tried mastadon but I can’t imagine it’s harder than lemmy. Plus they already would have more established apps.

The problem I have with Mastodon is you need people to get people. And if the people I personally know and follow just aren’t there, I don’t… have fun there. Lemmy is much easier because it doesn’t depend on personal people, but just communities. So even if there are few people, that’s still easy to get more people there because it doesn’t rely on many specific ones.

or just be a weirdo and reply to Lemmy comments from your Mastodon account like me. Then you don't need people on Mastodon since they're already on Lemmy.

Yeah, that’s true; but I kind of meant actually using Mastodon and its original content, not other ActivityPub content 😅
It’s really cool it’s possible like this though
