Introducing FingrPrintr: The Internet's Loneliest Social Network
This is an idea I had rolling around in my head for a while (I even had a beta version on heroku back when that was a thing), and I finally took a couple days to sit down and flesh it out.
It's built on Cloudflare Pages, which enables it to fully support browsers without JS!
