sorry for the delay! life in meatspace has been busy lately.

it looks like this site has some kind of dynamic loading happening. so rather than loading the post directly, their site loads a page with a bunch of JavaScript which then looks at the url and loads the content for that.

Readability (the library Slurp uses to generate simplified versions of web pages) generally can't handle sites like this since it would mean running third-party code outside of a sandboxed browser tab, which opens up a whole host security concerns.

I'll do a bit more digging when I have more time to dive into the code and see if there's something that can be done to work around that dynamic loading issue safely as it's been a problem elsewhere too, but I wouldn't get my hopes up.

One thing I can absolutely do though is improve the error message that pops up.
