I know what you mean, I’ve only been lurking around lemmy for the past month, but I’ve seen loads of subreddit-copy-paste communities spring up, some populated soley by content reposting bots. It seems that every other post is mentioning Reddit for one reason or another.

I think it’s natural, I think a lot of people are experiencing grief, feeling like they’ve lost something. I think that’ll go away in time, those communities that don’t get real activity will die, those that do will diverge from their subreddit progenitor, and lemmy originals will continue to exist/be born.

I hope new users evolve beyond Reddit culture though - with all the different instances, it’ll be interesting to if we end up with a single culture, or multiple cultures.
