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.
There is also https://brutalinks.tech/

It’s not a Lemmy frontend, but an unrelated project similar to Kbin that also uses ActivityPub to federate. I am however not sure how well it federates with Lemmy right now. Probably needs some testing and bug-fixing.
