We set up a bridge between the Lemmy.world General Matrix room and the Public-1 channel on the Lemmy World discord server yesterday. It’s not perfect as emoji reactions aren’t visible and some minor things like how it handles edited messages but other than that it seems to be working well.
Now people on both chat clients can interact with eachother!
I’ve personally been using Element and love it. I have a private matrix server for my family to use. Some of the members of the family have also loved FluffyChat.
