I personally don't mind Discord. I do in fact like it. (If you want to convince me otherwise, please don't)
But I really hate that OSS uses discord for their lack of documentation. I understand that documentation is hard and boring to create, but I don't want to go on some discord to ask a bunch of questions that thousands of others have before. Instead I will try and find something using search engines and I will read the open and closed issues. If I don't find anything, I give up on the software.
