> Subscribe to the blog's RSS feed?

Which has the 10 or 20 most recent posts, but not the post from 12 years ago. If it's a wordpress blog, you can use pagination tricks to get older posts, but, AFAIK, there's no standard way to say "Give me all of the posts" when fetching the RSS feed.

It is possible for feeds to support pagination and archives in a standardized manner: https://www.rfc-editor.org/rfc/rfc5005#section-3

Not very common though in my experience.

I sampled a few of my RSS feeds. Exactly zero of them implement this.

These days an awful lot of blogs don't have RSS feeds.

Especially blogs that are part of broader news publications, in my experience.

But yes you're right when there is a feed you can open that in Chrome and Ctrl+F, at least.

(Obviously my complaints come from blogs that don't have this. But also, opening an XML file isn't exactly user-friendly, and 99% of end users would never know to do it.)

But is it a blog if it doesn't have an RSS feed?

…okay sure, technically yes, but not one I will be able to follow, or remember to read until it pops up in someone else's aggregator or links in the future.

That's not my experience.
