A bit of a technical tangent, but I wonder if a peer to peer version of this website would increase its chances of survival. I can easily imagine something like a reference manager that puts copies of the PDFs you've read or written on IPFS. It would still require some central node that coordinates the sharing, but if some open source ActivityPub service would fill that role it could work I think. Provided there is of course enough personal incentive to share and keep sharing these works.
