I incidentally found this article on wiby when I was looking for information about OpenGraph.

"We were promised Strong AI, but instead we got metadata analysis" by Cal Peterson
The page has human readable source, and I copied and added the tags with "og:" to one of my webpages (the one about a vending machine in minetest).
Not feeling enthusiastic about the changes as it turns out OpenGraph is mainly for getting attention on platforms like Facebook, Twitter, and Discord which I don't have any presence on. But it's more effort to go back and erase the tags from my template.
Also a required property is og:image. For some of my pages, grabbing an image for the sake of a card on social media doesn't make sense. I'm also half-certain any images I use from neocities for og:image may instead get hotlink blocked.
I have to wonder how much of SEO is diverting focus away from creating meaningful content and towards adding metadata formats and gimmicks that may or may not obsolete over time. (Do XML site maps still get used?)
