I meant unique in the size and numbers of users. I think at a certain point, you will lose some beginner-friendliness if you want it to scale.
Dunno if it’s still true or not but I also recall that stuff like Lemmy depends on DNS, meaning you have to be able to buy your own domain and depend on that kind of central authority (wasn’t the point of Fediverse stuff to be decentralized?)
Well, then you could just as well call the web itself not enough dezentralized. The Fediverse just builds on that.
Rather recently a good amount of Lemmy servers were oopsied because one of the .tld authorities pulled the rug from under an entire top-level domain name.
