It makes sense.
Most people who came here two months ago did so because they explicitly wanted to leave Reddit, but not because of Reddit content or the site culture. It was because admin decisions on third party apps and the API.
They still wanted Reddit, just with different Admins and different apps. Ideally, they'd have wanted communities to fully migrate over.
lemmy.world specifically became basically a lifeboat, having been linked to from original third party apps.
Yes, it was created and had the technical and resource requirements to keep up with the new influx of users without constantly crashing (in the beginning), but nonetheless, that meant it got the largest influx of the migration.
It's honestly a bit strange for me to see people in here with two month old accounts saying "oh yeah the culture has just changed so much".
You all were the change. It's that influx of users that basically brought Reddit here.
Anyone who came here before the API changes did so either because they had some kind of issues with Reddit, whether it was the dominant culture or what, and wanted an alternative or because they were interested in the open source and federated nature of the project regardless of Reddit's own decisions.
Though tbf, pre migration, this place was basically dead. Posts would have a handful of comments at best and it was mostly Lemmygrad users and also FOSS enthusiasts. Hexbear was the most active Lemmy instance and was a chapotraphouse lifeboat formed in 2020 but it didn't federate so it was really mostly just Lemmy.ml as a general instance and Lemmygrad unless you explicitly knew and cared for Hexbear. Neither was very "toxic" in their own communities and there really wasn't much inter instance fighting, even if there still were people on lemmy.ml who didn't care for grad, as far as I remember. I honestly mostly lurked and didn't participate often.
The apps also were much worse.
Things started picking up as the API announcement happened. That's probably when we had the best balance of positivity and user growth.
It exploded when the API changes went into effect and voila.
Still, I would say it's mostly still a bit better than Reddit and there's more effort in commenting for the most part.
I don't think I've seen a pun chain or a "he's not your buddy, guy" or anything like that.
