Lemmy is cozy. I think it could be better if it were larger but not like, huge. But its also okay now. Not everything needs the grow at all costs mentality
I think Lemmy should be huge. Think about how many subreddits exist for every niche. It would be great if those places could exist free of corporate influence.
Lemmy's design is fundamentally unable to deal with bad actors. The only reason it's tolerable now is that it's too small to be worth their time. It would completely go to shit if it ever got huge.
Eh, if an instance allows trolls, then that instance typically gets defederated from very quickly (at least it does on my instance). The only reason it is an issue now is that two of the big three instances (.world and .ml) have very lax moderation standards. If the lemmy-verse grows to the size of Reddit, then two lax instances won't be as big of an issue.
