My local instance has quite a few active communities, but I still wish others were more active. One thing I really like is that the discussion in the comments seems to be more thoughtful and constructive.
Next on my to-do list is trying out the mobile apps. Maybe one of them will be like Apollo one day. The whole UI and UX is (still a few days) best in class.
The start has been really exciting and I look forward to seeing how both Lemmy and the fediverse in general develop. Fingers crossed 🤞
This is also something I really like. Dedicated forums for different topics, but this time they’re accessible through a single interface and you can communicate across forums.
