Gopher might be a good way to make my journal public.
I use my notes applications for journaling, it's a notebook within. These applications store notes as text files (more specifically, markdown). Gopher is just text files (mostly).
Seems logical.
Plus, once I figure out my deadman system, I can have a script simply copy the files from my non-public journal to public to put it all out there.
I just need to find a gopher host and hopefully an upload meyhod I can automate.
