Is anyone using ArchiveBox regularly? It's a self-hosted archiving solution. Not the ambitious decentralized system I think this comment is thinking of but a practical way for someone to run an archive for themselves. https://archivebox.io/
I am self-hosting ArchiveBox through yunohost, for the odd blog article I come across and like.
Not a heavy user per se, but it's doing its thing reliably.
I'd never heard of it, but their responses to question and comments in that thread were really really good (and I now have "install and configure archivebox on the media server" on my upcoming weekend projects list).
