Unfortunately, reddit has been too long and entrenched in society to “remove” it from our browsers. It is very different from Twitter or another social network. Lemmy is a great project. I hope it works and establishes itself as a real alternative, but it still has a long way to go. Unfortunately, the Reddit/Lemmy format is resource intensive, and that’s the problem with a service like this.
It’s my simple opinion. I support any fediverso project, but reddit, today I think it is irreplaceable.
