I am always amazed by how people mix everything and speak about thing they don't understand.
I think the message is pretty clear.
You want to discuss, chat, get troubleshooting, exchange with people, go to chatroom
You want to get technical data that will be true for the next 2000 years: go to wiki
You want to exchange on topic about complex thinking and new findings: go to forum
So the message his: go to the correct tool to do the correct thing.
For goat, and what happen if discord disappear ? We just move to the next tool that will help us communicate. As it's a tool to exchange short message and direct text, nothing of value will be lost.
After years of existence, discord didn't force us to pay anything. Heck I even paid my own money to thank them for this project. Amazing.
For mav, wikis are still getting updated, forum is still there but not flood anymore with "How can I install this mod ?" because now they flood the discord with it. But I see still lots of new post, but only the important one.
I will stop answering this post to not heat it, but wanted to give my humble opinion. No harm intented.
