I’ve recreated around 30 subreddits into communities with different icons and banners on my instance. Most of those communities remain empty, but I welcome anyone wanting to post content. You can check out some of the communities I created here. I don’t know if some topics are of your interest.
To respect the rules of the lemmy.world instance and community. I want to disclose that my server is nowhere near as powerful as the specifications of the lemmy.world server indicated in this post. Nevertheless, I started my own instance because I wanted to do my part and support the decentralized nature of federated social networks. I also believe we do not truly know what will happen after July 1, and whether or not the more populated lemmy instances such as this one will get overloaded.
