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.
I'd say this is the good thing about FOSS, even Iranian people can use it despite the US embargo. No one person nor a country should have the power to ban stuff from others.
