I have been playing with the idea of a documentation.org. Something publicly funded (mostly through corporate and individual donations) that hosts technical manuals, white papers, guides, links to video tutorials (likely YouTube), FAQs, and even links to Discord and/or forums if they exist. Documents are public, free to index (no login to view), version controlled and held in perpetuity.
Obviously there is much more to it, but I think we have reached a point where something like it is required.
