It's impossible to fork a community without large enough following.Also the original community still has the advantage of being the "default one" where all the searches and references will lead you to.
The fact that now anyone can speak to a large audience by typing in a few random thoughts with no challenge or editing is a very radical change to public speech. I suspect that there will always need to be some form of “filtering” required even with our new media for speech. I love free speech, but humans are fallible.
The mechanism for editing this new type of speech is a work in progress. I agree that improvements are needed. It’s a big responsibility.
Seems democratized enough to me.
