The issue with creating tech for such semantics is whether authors put in the effort to provide metadata. For example, rel=next/previous has been around forever but most webpages don't have them because they are not exposed in browsers or other clients. Other data mentioned in the examples like title and open graph tags are provided for search engines, Facebook previews, and such.

But is Fathom supposed to be for annotating your own web site, or analyzing others'? If the former, then I'm truly bewildered, but it's not clear which it is.

As for rel=next/previous, I don't use them because Google makes it clear that these will make it treat the whole sequence like one paginated document in the index, contrary to their original semantics. I'd love if someone could correct me on this.

I suspect it's against the website's interests. If you provide semantic marks, it makes it easier to crawl your website, extract the actual content, and leave the ads behind.

The <article> tag already makes it pretty easy.
