I feel like most of the problem would be physical hardware. Costly servers that would need to be able to meet Lemmy’s growing demands.
I’m not sure how much optimization from the software side can be done to reduce resource requirements. There’s certainly things that can be done to improve user experience though.
One aspect I’d love (and is apparently in the works) is swapping instances while keeping your history. A migration tool of sorts. Would help.
Still the roughness is sorta endearing in its own way. But I don’t think it’d be endearing to most people.
I think Lemmy’s biggest challenges are server stability, increased complexity to use (most don’t understand things like instances), and low awareness from others. I only learned about it a day or two ago. Signed up out of curiosity.
But if Lemmy gets even more popular then the various popular instances are going to be stressed. It looks unstable to newcomers who go back to Reddit.
I signed up for lemmy.world originally, constantly had gateway errors. Lemm.ee seems more stable due to lower traffic.
But others may not be able to recognize that. Even if they did, might not want to create new accounts for several instances and go back to starting from 0.
Ya need some miralax.
