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.
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.
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.
