I think the Redditors joining Lemmy will certainly change the culture, both for the better and for the worse. Comments got pretty toxic on Reddit while I feel like the toxic comments on Lemmy were rare.
BUT, that could be a sample size thing. I'm curious to see if the ratio of toxic comments per active user would have been the same.
More people = more problems I am certain but this is a social network and without people it will fail. We must all make an effort to be the change that we want to see in the world.
I don't foresee a problem in the immediate future aside from higher server load, but in terms of culture, only people who believe in a new social network will be willing to join.
In 5 years however when this is a great place to be, a large number of people will join who don't respect the legacy. The departure from Digg to Reddit felt like this too, I hope that the federation aspect will ensure this is longer lived.
remember... federation is your friend. federation gives you the freedeom to change house (instance) and/or look for better communities on any other federated instance from your own instance.
well, yeah, I wouldn't disagree but it's not like they aren't trying. I think with Mastodon the followers are a lot more important than the toots though. I would agree that posting history here is probably a bigger deal.
I haven't looked at the back end to understand what might be involved, but just configuring the instance has given me an appreciation for the complexities and challenges involved in getting a federated app running at scale.
