This post is a demo of the new feature of my website that requires a special secret in the URL to view! If you try to guess this link by incrementing the post numbers on my site, you'll get an error when viewing this one. It will only work with the special secret parameter added to the URL! It's obviously not as good as requiring actual authentication, but it's incremental progress on publishing more private/restricted content on my website!
This was inspired by the discussion at the IndieWeb Popup session on sensitive data.
