I am theoretically switching over from Reddit to Lemmy. Finding myself spending more time on Lemmy than on Reddit. Maybe it’s because I am limited to using the desktop and can’t aimlessly browse Reddit on my iPhone. Of late, the only subreddits I cared for were on sports and their matchday threads and r/watches. I found myself aimlessly browsing through r/AskReddit and asking and answering pointless questions.
Yeah, it would be a killer feature. I would have thought it would have been better to delete duplicates, but multi-community feeds would probably be better since it would be a bit more fault-tolerant. Maybe each instance which has a community which is part of a multi-community feed could even keep copies of posts from all of the communities in the feed so if one instance goes down, it can restore the posts as soon as the downed instance is back up.
