I thought this was cool because it worked even in my old browser. So cool I went to add their RSS feed to my feed reader. But then my feed reader got blocked by the system. So now it doesn't seem so cool.
This is a common mistake and the author is in good company. Science.org once blocked all of their hosted blogs' feeds for 3 months when they deployed a default cloudflare setup across all their sites.
A mistake by the author. I tried 3 feed readers, including one I wrote myself. None of them were following links. They just don't support cookies. There is more to the web than just browsers.
If the site author reads this: make an exception for https://www.owl.is/blogg/index.xml
