It should work a lot better than it does. For instance, Misskey had a one-line error that prevented Threadiverse posts, fixed by forks such as Firefish and Iceshrimp. You can post to Lemmy by @ ing the community itself. Sometimes federation issues are caused by not pinging everyone across different servers in the reply chain.

I really wish this was just a little bit more smooth, as I would much prefer to interact with you all directly from my RSS Iceshrimp lol
