I’m fairly new to the fediverse, but my understanding is that different platforms are supposed to be able to share content between them. I have always hated most social media and reddit was the only one whose layout I could stand, so my favorite fediverse platform is Lemmy. I do have a mastodon account but if I can get the same content here I’d rather just delete it and use a platform I like. Is that how it works? If so how do I do that/know when I’m doing it?
I’m not sure about all the same content, but you can see at least some Mastadon content and comments on Lemmy and vice versa. You’ll recognize them as they use a lot of #tags and will @ the user they are replying to, which have little use on Lemmy.
