At least in terms of the communities popping up. A lot of them (even ones I made), are just the Lemmy version of Reddit subs. Is that a good/bad thing? Time will tell, but at the moment I think it’s kinda funny of what’s happening.
To frame it a different way, there was nothing special about Reddit except the community, and that community can live anywhere.
What’s funny is not that a community migrated, because we’ve seen communities migrate before. But what’s funny is that the Reddit administrators didn’t expect it or don’t care.
I feel like there’s very little to be lost from having more niche hobby communities, at least. Those were the thing I used Reddit for the most, and I feel that they were generally non-toxic.
Good thing, personally, there is nothing wrong with reddit itself other than management, UI, and mods being abusive, permanently online types. And that can move anywhere.
