I own {{mylastname}}.com and have been making a small social network for everyone who shares my surname. (it's rare) I'm using Facebook's NLLB to translate posts to different languages since we are mainly split between the Americas and Europe.
I suspect this is true for almost every somewhat relevant subreddit. Everything has been captured, someone has taken control of the politburo and is defining the message. I've been using the site since 2008 and within the last couple of years it feels like you cannot post anything unless you know someone.
