I'm just getting familiar with lemmy fediverse and trying to make my way through it after getting out from reddit. I'm trying out liftoff app for android and I'm seeing way more double posts from different instances from same users. Same content from same users on multiple instances. I thought fediverse supposed to, You post in whatever instance you are and it'll be shared among all instances. I'm more confused now.

Lemme explain with subreddits.

You have /r/tech and /r/technology, right? Different subreddits, different communities. Somebody posts something on /r/tech and crossposts it to /r/technology. You're subscribed to both. You now see the same link twice.

That's exactly what's happening here, cross-posting to different communities. It's still the wild west out here, but I would expect a lot of these communities to solidify behind 2-3 "winners" over time, with the smaller ones becoming more niche.
