You mean the "app" that has no search and requires you to sign up to see anything, then pass some obscure initiation ritual by the mods, then be pestered with various bots. And that app doesn't even make money yet, wait until they decide to become profitable.
Sadly, it's a proprietary space, yes, but still.
The difference with "social" networks (and now the bad state of search engines) is that you actually get to be part of a community. As opposed to shouting in a loud bar to compete for likes to get heard better maybe if some algorithm likes you.
I tire of answering the same question hundreds of times
