Thanks for posting that direct link. The original post's link took me to other older posts by that profile's owner and I couldn't find the relevant one. Maybe something to do with needing to be logged in to that site or having different post sorting settings than default.

The issue of "what I see at a link, isn't what you see at the same link" seems to be getting worse, especially on social media. And a lot of sites no longer even care enough to provide an explicit Permalink.
