The disgusting reality of administering a MediaWiki wiki is that you're dealing with the world's ugliest most poorly designed and clunky software in the history of forever. This hell is where I came from.
People want to write. They want to contribute to humanity's general knowledge. They don't want to be assaulted with nasty error messages and clunky web hosting server bullshit and jibber jabber.
This is why the ad-infested cancer-causing Fandom site is so successful, because it's basically a wiki server farm which takes away the headache of administering the site yourself.
WeWrite aims to be the turnkey wiki, where writing is as easy as writing in Apple Notes. Remind me, when did you have to debug Apple Notes server code? (sorry for the Apple Engineers reading this, I'm speaking to normal people)
Let My People Write!
