I really like the concept of a federated message board. This is what I wanted for my life. However, Lemmy.ml is kinda difficult to surf through comments and it’s actually bothering me. It actually clones the new reddit, while the old reddit was much better in terms of reading.
The best thing about Lemmy is how it is completely separated from its UI. There are already different UIs available you can install to your instance or ask your admin to install. I think the LemmyBB might interest you: https://github.com/LemmyNet/lemmyBB
