The people who joined lemmy.world/one/whatever did it because they saw light and people. They are mostly spectators, not content creators.
The people who joined kbin saw an opportunity to restart from scratch, they are creators.
My experience so far is that the majority of the content on here is regarding reddit/subreddits/reddit activity.
If this is the type of content that continues to get posted/traction, then this place will collapse
keep in mind that there’s already lots of content coming in from Lemmy, and kbin can be another way to access that content in a manner some people prefer. the biggest advice for everyone is to be the change you want to see. we can’t just be lurking consumers if we want to be here, we have to start commenting and posting all we can
