I was against it at first, but there’s probably a lot of value in communities spinning up their own domains and hosting their own focused communities. Instead of a central Lemmy.world which hosts many different communities, we should have lemmyPics.com and lemmyMusic.com and MaleFashionAdvice.com that all run Lemmy software, and then people can subscribe in from remote instances easily.
There’s still a place for general instances in this model too, but I think these communities might get off the ground easier with a $12 domain name and cloud hosting services than trying to all be the next Reddit.
